Performance Desktops

2009-05-01T12:05:00.000+07:00

If you need maximum computing power for gaming or video editing, here are the specs you need to keep in mind when PC shopping.

PROCESSOR

Power users need the best, and that means quad-core. AMD's Phenom line and Intel's Core 2 Quad, Core 2 Extreme, and newest Core i7 families of processors offer four-core solutions that will give you maximum power and the best possible protection from technology extinction. Want even more juice? Look for a processor that the manufacturer has overclocked (pushed to a higher speed rate), or one with an unlocked multiplier so you can tweak it to your own specifications. You might need to pay more attention to cooling with overclocked CPUs, but the speed bump you get might be worth it.

MEMORY

Don't consider anything less than 2GB—it's the bare minimum you need for a good experience in Vista. Also check to see whether your machine uses DDR2 or newer DDR3 RAM. The latter, which is used exclusively with Intel's new Core i7 family of processors, can operate at faster speeds but is also more expensive, and you can't use DDR2 RAM in DDR3 sockets, which might cause problems if you want to upgrade later. Also pay attention to RAM speeds, measured in megahertz (MHz): The higher the rated speed, the better the RAM will perform—assuming your motherboard supports the speed.

GRAPHICS

It took the gaming industry a while to catch up to the DirectX 10 (DX10) train, and now that it has, most of the biggest titles use it. Since DX10 is more demanding (and visually impressive) than its predecessor, DX9, you'll want the most powerful card you can afford—look for one with at least 512MB of graphics memory, and get more if you can swing it. If you have deep pockets, go for a multiple-card setup using nVidia's Scalable Link Interface (SLI) or ATI's CrossFire technology—depending on your hardware, you can use up to four graphics cards in each setup for the maximum in image-crunching potential.

HARD DRIVE

The faster a drive's rotational speed, the better your system will respond, and the quicker your applications and games will start. Though 15,000rpm drives are available, they're noisy and cost-prohibitive—stick with a 10,000rpm drive for your OS and programs. Complement that with a second drive of 200GB or larger for bulk storage.

OPTICAL DRIVES

Two DVD±RW drives is overkill—go with one DVD burner and a DVD-ROM drive, and you should be all set. High-capacity Blu-ray drives are becoming increasingly popular, but few PC games at this point require them, so you probably won't need to bother with one yet. Adding one to your system later will run you about $200 if you want just a reader—or around $500 if you want one that writes Blu-ray discs, too.

CASE

Performance PCs need space for both components and cooling, and a full-tower case provides the room for both. Make sure airflow is adequate and that the case provides enough bays to add drives later. Some performance-PC makers offer liquid-cooling systems as an option, but it's unnecessary unless you have extraordinary cooling needs (say, for overclocked components) or are trying to reduce operating noise. (In the latter case, you can quiet a PC far more inexpensively by opting for larger, slower-spinning fans.) If you plan on running multiple graphics cards, pay attention to your rig's power supply (you might need a unit that can pump 700 watts or more), and the number of expansion slots available (the newest cases come with 10, to accommodate four-card SLI and CrossFire setups). Also, look for USB, FireWire, external Serial ATA (eSATA), and audio inputs on the case's front panel for easy access. A multiformat memory-card reader is convenient, too.

SOUND

Definitely spring for a dedicated sound card. The speakers included with a PC in this price range should take full advantage of the sound card's abilities. Most top cards support immersive 7.1-channel surround sound. Whether you want seven or eight speakers (and the wires they entail) is your call.

MONITOR

You'll definitely want a monitor that takes advantage of the power of your graphics card. Look for a wide-screen LCD monitor measuring at least 20 inches. (A 24-inch monitor will have enough pixels to play Blu-ray movies in their full 1080p resolution, and allow you to blast through games on a 1,900x1,200 desktop.) Also pay special attention to the LCD's pixel-response time: the lower that number, the smoother the picture. Gamers will want a 6-millisecond or faster pixel-response rate.

Budget Desktops

2009-05-01T12:02:00.000+07:00

Today's budget PCs deliver adequate power for most home users. Here are tips on how to get the most for the least money.

PROCESSOR

You'll pay a premium for the fastest processor, so go with a CPU a couple of cycles behind the top clock speed. It’ll save you money while still yielding a PC with plenty of power for everyday tasks. You likely won’t get a cutting-edge, quad-core processor in a budget PC, but dual-core CPUs have become significantly inexpensive, offering decent performance for a relatively low price. (You’ll need one to take full advantage of Windows Vista.)

GRAPHICS

As a rule, budget PCs use integrated graphics that share system memory and generally can't handle complex games and graphics. Most onboard graphics systems, however, have more than enough power to display the full slate of attractive Aero effects in Windows Vista. Scout out a desktop with a PCI Express (PCIe) x16 slot, which will let you add a dedicated graphics card later. Opting for a basic video card (either at checkout or later on) will cost you about $60 more than settling for integrated graphics—but if you want to do anything more than basic 3D tasks, it’s a worthwhile investment.

MEMORY

More is always better. 1GB should be fine for Vista Business or Vista Home Basic, and you can get away with 512MB for Windows XP—but if your computer will run Vista Home Premium or Vista Ultimate, don’t settle for less than 2GB. Memory prices have dropped drastically, so there’s no excuse not to load up; not getting enough will cause slowdowns that probably aren’t worth tolerating considering the money you’d save.

HARD DRIVE

If you plan to load your desktop just with Microsoft Office files, a little music, and some digital images, you can get by with an 80GB drive, the budget standard. We're pack rats, though, and with drives as cheap as they are, we wouldn't dream of settling for less than 120GB for an average home machine. Consider getting 250GB or more if you plan on using your computer to listen to digital music or download video files.

OPTICAL DRIVES

Two optical drives (recordable DVD, DVD-ROM, or CD-RW) are better than one. To cover all your bases, we recommend getting a DVD±RW drive (which can burn both DVDs and CDs) and a DVD-ROM (which can only read DVDs and CDs). If you can only afford one, go with the DVD recorder—drive prices are cheap enough these days to justify the few extra bucks.

CASE

Most budget PCs use minitower or midtower cases. If you think you'll want to upgrade or add components later, make sure the case has room for expansion.

SOUND

You'll be hard-pressed to find anything but a motherboard-integrated audio chipset in a budget PC—few provide a dedicated sound card. Integrated audio is fine for general use but tends to lack sufficient power for listening at loud levels. It may not support surround sound, either. A quality sound card costs approximately $50 more than onboard audio. Also, don't expect the standard bundled speakers to be high-quality. You might find a budget system with a three-piece speaker set (two satellites and a subwoofer), but two-piece sets are the norm.

MONITOR

CRT monitors are still available on a limited basis, but the prices for LCDs have dropped so much that it doesn't make sense to buy a bulky CRT anymore. Most budget systems that include monitors come with a 15-inch display, but upgrading that to a 17-inch LCD won't cost much. Plus, those extra inches make a big difference in viewing comfort.

Midrange Desktop

2009-05-01T12:00:00.000+07:00

A good midrange PC will include highly capable components that can handle all your everyday computing tasks. Here's what you need to know about processors, RAM, graphics cards, storage, and more.

PROCESSOR

Don't choose an underpowered processor, but look at CPUs one or two steps down from the fastest to get the power you need at a good price. Multi-core chips feature more than one processing core on a single CPU; choose either a dual-core option from Intel’s Core 2 Duo line or a four-core CPU from AMD’s Phenom series for solid performance in Windows Vista and most other software apps. Besides, if you do heavy-duty multitasking, you won’t want anything less.

MEMORY

The more memory you have, the better your system will run. Insist on at least 2GB for Windows Vista Home Premium or Vista Ultimate; otherwise, 1GB should be sufficient.

GRAPHICS

To ensure you’ll have enough power for most basic tasks—including moderate video editing and 3D gaming—and that you can see Vista in all its graphical glory, go with a 256MB or higher card. Video card makers nVidia and AMD have many great options available for $100 or less.

HARD DRIVE

Opt for two hard drives of at least 160GB apiece, configured in a RAID Level 1 array to ensure your data is always backed up. If you have a large video or digital-music collection, you should future-proof your purchase by considering a larger drive.

OPTICAL DRIVE

Opt for a DVD±RW drive as your first choice. Two drives are better than one, though, so go with a fast CD-RW, DVD-ROM, or DVD-ROM/CD-RW combo model for the second.

CASE

Be certain the case offers adequate expansion room, and look for a few conveniently placed front-panel ports and audio jacks. In this price range, we like to see a multiformat flash-memory-card reader built in, too. Also, make sure the power supply can handle current and future components; a 400-watt supply is a safe bet.

SOUND

Integrated sound is common, and superior to what you'll find in budget desktops. A dedicated sound card is still a better choice, however. It should cost roughly $70 to upgrade from integrated audio to a high-quality card.

MONITOR

With CRTs all but dead, chances are your next monitor will be an LCD. As with other tech, the lower the cost, the fewer the features. The first things to go are digital inputs and ergonomic adjustments; less-costly LCDs also tend to have lower resolutions and slower response times (which can lead to "ghosting"—image distortion that can occur during the fast-moving action of a game or movie). For general, everyday use, don't go smaller than a 17-inch LCD (unless you like squinting); 19-inch displays are the new mainstream size. Also consider wide-screen LCD monitors: They're great for viewing documents side by side and for watching letterboxed DVD movies.

Entertainment Desktop

2009-05-01T11:56:00.001+07:00

An entertainment desktop will enable you to watch and record TV programming on your PC, as well as make the most of your digital music, video, and images.

PROCESSOR

You don’t need the fastest available processor to take advantage of the Media Center features in Windows Vista Home Premium or Ultimate. Get a CPU one or two steps down from the fastest, but make sure it’s at least a dual-core, a must for surviving the multitasking entertainment required by PCs. Also, consider getting a system that uses a mobile processor. Though somewhat less powerful than their desktop equivalents, these chips generally use less power and give off less heat, meaning you’ll save more on energy and will need fewer noisy fans inside your case.

MEMORY

The more memory you have, the better your system will run. You’ll want a minimum of 2GB for running Vista.

GRAPHICS

You can get away with integrated graphics, but we recommend a dedicated graphics card with at least 256MB to take some of the edge off Media Center’s intensive processes. This should also give you enough power for video editing and modest 3D gaming. If you plan to watch protected high-definition (HD) content, buy a card that supports High-Bandwidth Digital Content Protection (HDCP) decoding; some also have HDMI ports for outputting video and audio signals to an HDTV.

HARD DRIVE

Media files—especially digital video—take up a lot of space. Go with the largest drive you can afford, and definitely select nothing smaller than 250GB (500GB would be even better.) A multidrive RAID Level 1 array ensures your data is always backed up, which is essential if you’re storing your digital audio, video, and photography on your hard drive.

OPTICAL DRIVES

A DVD±RW drive should be your first choice for storing and sharing your media, and it should be at least a double-layer. You’ll want another drive (probably a DVD-ROM) for copying discs. Consider getting a Blu-ray drive, too: If you just want a reader for watching HD movies, you can add one for around $200; one that also burns high-capacity Blu-ray discs will run you $500 or more. Combo drives that read Blu-ray and write to DVD and CD are a reasonably priced compromise.

CASE

An A/V-style case looks best in the living room. Alternatively, you can opt for one of the ultra-small-form-factor PCs available from companies such as WinBook and Shuttle. Keep in mind, though, that their low-profile enclosures leave little room for internal expansion.

SOUND

Integrated six- or eight-channel sound will suffice, but audiophiles will prefer a dedicated card. Expect to pay about $70 more for a high-quality dedicated card in place of onboard audio.

MONITOR

If you intend to use your computer for work and entertainment, we recommend a dedicated computer monitor. Definitely go for a wide-screen LCD so you have the most screen real estate available (and for playing movies in their original aspect ratio). Televisions, on the other hand, are not ideal for general computer use unless they have an RGB or DVI connection. If you want to pair your PC with an HDTV, be aware that Media Center supports only broadcast HDTV; you'll also need an external antenna for reception.

Warranties and Service Plans for Desktops and Notebooks

2009-05-01T11:54:00.000+07:00

A solid warranty is an essential part of every PC purchase. Here are tips for getting all the protection you need when shopping for a new desktop or notebook.

WARRANTY TERM

Major vendors such as Gateway and Lenovo are attempting to set the standard term for warranty coverage at 90 days, but no PC owner should settle for a plan that short. If you're faced with coverage shorter than one year, consider buying an extended service plan. Note, though, that in most cases you must purchase the extended plan before the standard warranty expires.

PARTS COVERAGE

As a rule, standard warranties cover your computer's main hardware components (CPU, hard drive, RAM, optical drive). Software and peripherals, such as monitors and keyboards, are usually covered by their manufacturers' warranties or by an optional service plan. Keep in mind that extended service plans for PCs still won't cover these extras—they only lengthen the coverage period of the standard warranty.

DAMAGE PROTECTION

Under a standard warranty, vendors will repair computers damaged during shipping or that have defective parts. Notebook owners and the accident-prone should invest in an accidental-damage protection (ADP) plan to insure their laptops against drops, spills, and regular wear and tear. ADP plans aren't available in all states, however.

REPAIRS

Many vendors offer depot service, which requires you to return a PC to an authorized factory or service center for major repairs and parts replacement. Another option is a service plan that includes onsite repair, under which a computer technician will visit your home to fix your PC, usually by the next business day. Note that a host of eligibility restrictions usually apply to getting onsite service—carefully examine the service contract before buying.

TECHNICAL SUPPORT

Support via phone and online chat are generally the most effective ways to get help, but an easily navigable online knowledge base can help you solve simple computer problems at home without waiting on hold.

TERMS AND CONDITIONS

While the same warranty and support policies typically apply across most of a given vendor's offerings, specific terms and conditions sometimes vary by system or system line. Always carefully review the terms for your exact model before buying.

Budget Laptops

2009-05-01T11:50:00.001+07:00

You can get a capable notebook with plenty of memory, storage, and optical-drive options for $1,000 or less. Here's what you need to know before you buy.

PROCESSOR

Many low-cost systems come equipped with dual-core CPUs like Intel’s Core Duo and Core 2 Duo and AMD's Turion processors. These mobile chips deliver longer battery life, stronger performance, and cooler running temperatures than mobile CPUs of yesteryear. Save a little money by opting for lower clock speeds, such as 1.6GHz or 1.8GHz, which still offer enough power to handle Microsoft's Windows Vista OS. Tiny netbooks are using Intel's Atom low-power mobile processor, which is currently a single-core chip, but a dual-core Atom is due later this year.

MEMORY

Inadequate system memory can drastically reduce overall performance, so don't be too frugal. If you can afford it, we recommend 2GB of DDR2 SDRAM, which will boost overall performance and keep Windows Vista running smoothly. 512MB or 1GB is adequate for netbooks running Linux or Windows XP. Also, be on the lookout for any free memory upgrades at time of purchase—many PC makers offer specials that double the amount of installed RAM.

GRAPHICS

Most low-cost laptops will disappoint gamers because they use more-affordable integrated graphics rather than dedicated 3D chips. When coupled with at least 1GB of RAM, Intel's latest GMA X3100 graphics chipset does support Windows Vista and its graphics-intensive Aero interface. You may find a few budget notebooks with lower-end dedicated chips, however, such as the ATI Radeon HD 2400 or nVidia GeForce 8400M. While they won’t rip through the latest titles at the highest resolutions, these Vista-compatible cards should satisfy casual gamers with their 128MB or 256MB of dedicated video RAM and DirectX 10 support.

HARD DRIVE

As hard-drive prices drop, larger models have started to trickle down into budget notebooks. The more storage you can afford, the better, especially if you have a big digital media collection. We’ve seen low-cost systems with drives as big as 250GB. While slower 4,200rpm hard drives cost less, opt for a drive with a rotational speed of 5,400rpm. Some netbooks forgo traditional hard drives in favor of a solid-state drive (SSD), which offers a faster boot time, lower weight, and increased resistance to shock. Budget-price SSDs are often very low in capacity, however—8GB is a popular drive size.

OPTICAL DRIVE

Go for a multiformat (DVD±RW) DVD burner, which writes to both plus- and minus-format DVD media. If you have no need or desire to burn DVDs, a DVD-ROM/CD-RW combo drive, which burns only CDs, will serve you well. Netbooks aren't big enough to come with an internal optical drive.

CASE

In terms of size and weight, budget notebooks span every category, from itty-bitty ultraportables that weigh less than 3 pounds to hulking desktop replacements that can be more than 7 pounds. What size you choose should depend on your need for portability, though keep in mind that the plastic cases typically used for budget notebooks aren’t the most durable. You’ll still find plenty of budget models with bland-looking black or gray cases, but some manufacturers offer a more exciting variety of color options and designs for their low-cost systems.

WIRELESS CONNECTIVITY

Integrated 802.11 wireless networking (Wi-Fi) is an essential feature. Look for a notebook with a Wi-Fi card that supports the 802.11a, g and Draft N wireless standards. Draft N makes use of multiple-input, multiple-output (MIMO) technology, which reduces signal interference and provides greater range and throughput, up to a theoretical maximum bandwidth of 300Mbps. Budget notebooks typically do not include Bluetooth wireless connectivity, although most manufacturers give you the option to add it.

DISPLAY

Although many budget laptops sport a 14.1- or 15.4-inch wide-screen LCD, notebook screen sizes can range from 7 to 17 inches. Most displays come with a glossy coating that provides a better viewing experience when watching movies. Some people don't like the reflectivity of these glossy screens, however, so be sure to check out a laptop's display in person before you buy. If you want to use your laptop for video conferencing, be sure your screen comes with a built-in Webcam, or that the notebook’s manufacturer offers one as a configuration option. If you want to use your notebook for video conferencing, opt for a system with a Webcam built in to its display bezel.

Desktop-Replacement Laptops (More Than 7 Pounds)

2009-05-01T11:47:00.000+07:00

If you're looking for a powerful laptop with a potent feature set—a large display, a discrete graphics card, a full-size keyboard, and the latest processor—consider a desktop replacement.

PROCESSOR

When you’re choosing a CPU, configure your notebook with a powerful processor such as Intel's Core 2 Duo or AMD's 64-bit Turion 64 X2. For maximum power (and longevity) from a mobile CPU, strongly favor the Core 2 Extreme if it's an option. Some large desktop-replacement systems can be configured with Core 2 Duo, Core 2 Quad, and Core 2 Extreme desktop processors. While these speedy chips are a great choice for increased performance, be aware that they often run hotter and drain battery power faster than mobile processors.

MEMORY

Don't be frugal with your system's RAM—inadequate memory can drastically slow overall performance. You'll want at least 1GB, but gamers and power users should aim for 2GB or higher. As for the memory speed, 533MHz DDR2 SDRAM will support the Windows Aero interface, but we recommend 667MHz or faster for better overall performance. Some vendors may offer the option to add Intel Turbo memory to your system. These flash-memory modules, available in 512MB or 1GB varieties, reduce the time it takes for your computer to power up, access programs, and write data to the hard drive.

GRAPHICS

If you play games, opt for the latest graphics processor with dedicated memory from ATI or nVidia. Some newer notebooks even manage to pack two video cards in a Scalable Link Interface (SLI) configuration. If you're not a gamer, save a little money by opting for 256MB of dedicated graphics RAM, a decent mount for running Windows Vista's Aero interface. You should avoid integrated graphics.

HARD DRIVE

A 100GB drive may be plenty of space for casual users, but those who have large digital media collections, play lots of advanced games, or edit digital video should opt for 250GB or more. We’ve seen desktop replacement notebooks with drives as large as 500GB, and some can even be configured with two drives in a RAID Level 0, RAID Level 1, or RAID Level 2 configuration. Make sure each drive has a rotational speed of at least 5,400rpm; some high-end notebooks offer desktop-caliber drives spinning at 7,200rpm, though you'll pay a premium for the speed increase. In addition to standard hard drives, some vendors have introduced solid-state drive (SSD) options for their desktop notebooks. These flash-memory-based drives, which have no moveable parts, offer faster boot times, lower weight, and increased resistance to shock. This technology is currently quite expensive, however, and drive capacity is usually limited to 32GB or 64GB. Unless having the added durability and speed boost is a must, we recommend sticking with a traditional hard drive.

OPTICAL DRIVE

Look for a multiformat (DVD±RW) DVD burner, which writes to CDs as well as plus- and minus-format DVD media. The drive's write speed is a secondary consideration, and slower drives are cheaper. Several desktop replacement notebooks can be configured with a high-definition Blu-ray drive, which can play compatible HD movies and write up to 50GB of data to dual-layer Blu-Ray disc. This upgrade is pricey, however.

CASE

Don't be put off by heft and weight, because you probably won't be traveling much with a desktop-replacement notebook. Powerful components do tend to run hot, though, so ensure that the case provides proper ventilation. Note that magnesium and other molded-metal enclosures usually dissipate heat better than plastic cases do.

WIRELESS CONNECTIVITY

Integrated Bluetooth and 802.11 wireless networking (Wi-Fi) are essential features. Look for a notebook with a Wi-Fi card that supports the 802.11a, g and Draft N wireless standards. Draft N makes use of multiple-input, multiple-output (MIMO) technology, which reduces signal interference and provides greater range and throughput, up to a theoretical maximum bandwidth of 300Mbps. Bluetooth is also standard on many laptops, though some configurations provide it only as an option. For maximum compatibility with other Bluetooth devices, make sure your laptop supports Bluetooth 2.1 + Enhanced Data Rate (EDR). If you want to be able to get online when you’re out of range of Wi-Fi networks, look for notebooks that can be configured with a built-in WWAN module, which lets you tap into a cellular mobile broadband networks from Verizon, Sprint, or AT&T for a monthly fee.

DISPLAY

Since portability is not an issue, look for a wide-screen 15.4-inch or larger display; for crisp text and smooth DVD or Blu-ray movie playback, go with the maximum resolution available on the screen size you choose. Whether you'll be watching movies in all their letterboxed glory or merely viewing several documents at once, more screen real estate is always better. While the sweet spot for desktop replacements is 17 inches, we’ve seen screens as large as 20 inches. LCDs are still the norm, but look for notebooks with displays that use LED backlighting instead of the traditional fluorescent tubes, which offers less weight and increased power savings. Many screens now come with a reflective coating that provides a better viewing experience when watching movies. Some people don't like the reflectivity of these glossy screens, however, so be sure to check out a laptop's display in person before you buy. If you want to use your notebook for video conferencing, opt for a system with a Webcam built in to its display bezel.

Ultra Portable Laptop

2009-05-01T11:41:00.001+07:00

The latest ultraportables pack features you'd expect from larger laptops, including integrated optical drives and roomy keyboards. They still won't replace your desktop, but they're highly able on the road.

PROCESSOR

Many top-of-the-line ultraportables now carry Intel's Ultra Low Voltage (ULV) Core 2 Duo CPUs, and these are your best choice for powering Microsoft's Windows Vista OS. Ultraportables are largely valued for their portability, not their speed; clock speeds as low 1.06GHz, 1.2GHz, and 1.6GHz should offer plenty of power for on-the-road productivity chores. Budget ultraportables mostly use Intel's Atom low-power mobile processor.

MEMORY

Having adequate RAM is crucial for fast performance, especially when running multiple apps. Though Linux-based budget ultraportable can get away with as little as 512MB, we recommend opting for at least 2GB of DDR2 SDRAM if you're running Windows Vista. Some vendors may offer the option to add Intel Turbo memory to your system. These flash-memory modules, available in 512MB or 1GB varieties, reduce the time it takes for your computer to power up, access programs, and write data to the hard drive.

GRAPHICS

To keep their size and battery life in check, ultraportables often forgo dedicated 3D chips in favor of integrated graphics. When coupled with 1GB of RAM, Intel's latest GMA X3100 graphics chipsets do support Windows Vista and its graphics-intensive Aero interface.

HARD DRIVE

Since you probably won't be storing lots of digital media files or editing video on an ultraportable, an 80GB or 100GB drive should be adequate. In addition to standard hard drives, some vendors have introduced solid-state drive (SSD) options for their ultraportable notebooks. These flash-memory-based drives, which have no moveable parts, offer faster boot times, lower weight, and increased resistance to shock. This technology is currently quite expensive, however, and drive capacity is usually limited to 32GB or 64GB. Unless having the added durability is a must, we recommend sticking with a traditional hard drive.

OPTICAL DRIVE

To maintain their slim profiles, ultraportables often don't include built-in optical drives. Of those that do, some include internal DVD-ROM/CD-RW combo drives or multiformat (DVD±RW) DVD burners, which write to both plus- and minus-format DVD media. A few allow you to swap out the optical drive for an extra battery.

KEYBOARD

Due to their compact size, many ultraportables feature smaller-than-usual keyboards and touch pads. In some cases, the keys themselves are actually slimmer or truncated, making it difficult for touch typists to find their way around the keyboard. If possible, try out the keyboard before you buy.

CASE

Look for a model with a case that's durable, preferably one made from a metal alloy. By definition, an ultraportable notebook should weigh less than 4 pounds. You can find ultraportables as light as 2 pounds.

WIRELESS CONECTIVITY

Integrated Bluetooth and 802.11 wireless networking (Wi-Fi) are essential. Look for a notebook with a Wi-Fi card that supports the 802.11a, g and Draft N wireless standards. Draft N makes use of multiple-input, multiple-output (MIMO) technology, which reduces signal interference and provides greater range and throughput, up to a theoretical maximum bandwidth of 300Mbps. Bluetooth is also standard on many laptops, though some configurations provide it only as an option. For maximum compatibility with other Bluetooth devices, make sure your laptop supports Bluetooth 2.1 + Enhanced Data Rate (EDR). If you want to be able to get online when you’re out of range of any Wi-Fi networks, look for notebooks that can be configured with a built-in WWAN module, which lets you tap into a cellular mobile broadband networks from AT&T, Sprint, or Verizon for a monthly fee.

DISPLAY

Ultraportables' screen sizes typically range from 7 to 13.3 inches. Opt for a model with the largest possible screen. While LCDs with traditional fluorescent tubes are still the norm, look for notebooks with LED-backlit displays—they’re lighter and offer increased power savings. Many screens now come with a reflective coating that provides a better viewing experience when watching movies. Some people don't like the reflectivity of these glossy screens, however, so be sure to check out a laptop's display in person before you buy. If you want to use your notebook for video conferencing, opt for a system with a Webcam built in to its display bezel.

Thin and Light Laptop

2009-05-01T11:28:00.002+07:00

Providing the best of both worlds, a thin-and-light laptop is powerful enough for any task you throw its way, yet light enough to take on the road.

PROCESSOR

Look for a model powered by Intel's Core 2 Duo processor, which provides long battery life, strong performance, and cool running temperatures. If you're interested in purchasing an AMD-based laptop, go with the Vista-friendly Turion 64 processor.

MEMORY

Having adequate RAM is crucial for fast performance, especially when running multiple apps. Running Windows Vista requires at least 512MB, though we recommend opting for 2GB of DDR2 SDRAM, which will boost overall performance and keep Vista running smoothly. Also, be on the lookout for any free memory upgrades at time of purchase—many PC makers offer specials that double the amount of installed RAM. Some vendors may offer the option to add Intel Turbo memory to your system. These flash-memory modules, available in 512MB or 1GB varieties, reduce the time it takes for your computer to power up, access programs, and write data to the hard drive.

GRAPHICS

Most thin-and-light laptops will disappoint gamers because they forgo dedicated 3D chips in favor of integrated graphics, which not only cost less but help reduce the heft of the laptop case. When coupled with at least 1GB of RAM, Intel's latest GMA X3100 graphics chipset does support Windows Vista and its graphics-intensive Aero interface. You may find a few thin-and-light notebooks with lower-end dedicated chips, however, such as the ATI Radeon HD 2400 or nVidia GeForce 8400M. While they won’t rip through the latest titles at the highest resolutions, these Vista-compatible cards should satisfy casual gamers with their 128MB or 256MB of dedicated video RAM and DirectX 10 support.

HARD DRIVE

When it comes to storage space, the more gigabytes you can get, the better— especially if you have a big digital media collection. We’ve seen thin and light systems with drives as big as 320GB. While slower 4,200rpm hard drives cost less, opt for one with a rotational speed of 5,400rpm. In addition to standard hard drives, some vendors have introduced solid-state drive (SSD) options for their thin-and-light notebooks. These flash-memory-based drives, which have no moveable parts, offer faster boot times, lower weight, and increased resistance to shock. This technology is currently quite expensive, however, and drive capacity is usually limited to 32GB or 64GB. Unless having the added durability is a must, we recommend sticking with a traditional hard drive.

OPTICAL DRIVE

Go for a multiformat (DVD±RW) DVD burner, which writes to both plus- and minus-format DVD media. If you have no need or desire to burn DVDs, a DVD-ROM/CD-RW combo drive, which burns only CDs, will serve you well. A few thin-and-light notebooks can be configured with a high-definition Blu-ray drive, which can play compatible HD movies and write up to 50GB of data to dual-layer Blu-ray disc. This upgrade is pricey, however.

CASE

A laptop chassis more than 1.5 inches thick or heavier than 6 pounds (without AC adapter) exceeds the bounds of the thin-and-light class. Look for a model with a case that's durable, preferably one made from a metal alloy. You’ll find plenty of thin-and-lights with bland-looking black or gray cases, but some manufacturers offer more exciting color options and designs.

WIRELESS CONECTIVITY

Integrated Bluetooth and 802.11 wireless networking (Wi-Fi) are essential. Look for a notebook with a Wi-Fi card that supports the 802.11a, g and Draft N wireless standards. Draft N makes use of multiple-input, multiple-output (MIMO) technology, which reduces signal interference and provides greater range and throughput, up to a theoretical maximum bandwidth of 300Mbps. Bluetooth is also standard on many laptops, though some configurations provide it only as an option. For maximum compatibility with other Bluetooth devices, make sure your laptop supports Bluetooth 2.1 + Enhanced Data Rate (EDR). If you want to be able to get online when you’re out of range of any Wi-Fi networks, look for notebooks that can be configured with a built-in WWAN module, which lets you tap into a cellular mobile broadband networks from Verizon, Sprint, or AT&T for a monthly fee.

DISPLAY

You’ll find thin-and-light notebooks with screen sizes ranging from 12.1 inches to 15.4 inches; for crisp text and smooth DVD or Blu-ray movie playback, go with maximum resolution available on the screen size you choose. While LCDs are still the norm, look for notebooks with displays that use LED backlighting instead of the traditional fluorescent tubes, which offers less weight and increased power savings. Many screens now come with a reflective coating that provides a better viewing experience when watching movies. Some people don't like the reflectivity of these glossy screens, however, so be sure to check out a laptop's display in person before you buy. If you want to use your notebook for video conferencing, opt for a system with a Webcam built in to its display bezel.

Tablet PCs

2009-05-01T11:24:00.000+07:00

If you want to use your laptop to write as well as type, a Tablet PC is the perfect fit. Our buying advice will help you pick the perfect convertible notebook.

PROCESSOR

Look for a model powered by Intel's Core 2 Duo processor, which provides long battery life, strong performance, and cool running temperatures. If you're interested in an AMD-based laptop, go with one using the Vista-friendly Turion 64 CPU.

MEMORY

Inadequate system memory can drastically reduce overall performance, so don't be frugal. 512MB is the absolute minimum requirement for running Windows Vista; if you can afford it, we recommend 2GB of DDR2 SDRAM, which will boost overall performance considerably. Also, be on the lookout for any free memory upgrades at time of purchase—many PC makers offer specials that double the amount of installed RAM. Some vendors may offer the option to add Intel Turbo memory to your system. These flash-memory modules, available in 512MB or 1GB varieties, reduce the time it takes for your computer to power up, access programs, and write data to the hard drive.

GRAPHICS

Coupled with at least 1GB of RAM, Intel's latest GMA X3100 graphics chipset does support Windows Vista and its graphics-intensive Aero interface. If you use graphic-intense apps at work—or you want to use your machine to play games after hours—go with a dedicated graphics card from ATI or nVidia. For maximum stability and business-optimized performance, look for notebooks with nVidia’s Quadro NVS series; be sure the card you choose has at least 128MB (preferably 256MB) of dedicated video RAM.

HARD DRIVE

When it comes to storage space, the more gigabytes you can get, the better— especially if you save lots of large documents and PowerPoint presentations on your PC. We’ve seen tablet PCs with drives as large as 320GB. While slower 4,200rpm hard drives cost less, opt for one with a rotational speed of 5,400rpm.

In addition to standard hard drives, some vendors have introduced solid-state drive (SSD) options. These flash-memory-based drives, which have no moveable parts, offer faster boot times, lower weight, and increased resistance to shock. This technology is currently quite expensive, however, and drive capacity is usually limited to 32GB or 64GB. Unless having the added durability is a must, we recommend sticking with a traditional hard drive.

OPTICAL DRIVE

Smaller convertible notebooks often don't include built-in optical drives. Of those that do, some include internal DVD-ROM/CD-RW combo drives or multiformat (DVD±RW) DVD burners, which write to both plus- and minus-format DVD media. A few allow you to swap out the optical drive for an extra battery.

CASE

You won’t find too many flashy-looking tablet PCs out there—most manufacturers opt for black or gray cases that, though a bit staid, blend in well in a professional environment. As for weight, tablet PCs tend to range from around 2.5 to 6.5 pounds. What size you choose should depend on your need for portability, but always look for a case made of magnesium and other molded-metal enclosures, which are more durable and dissipate heat better than plastic cases.

WIRELESS CONECTIVITY

Integrated Bluetooth and 802.11 wireless networking (Wi-Fi) are essential. Look for a notebook with a Wi-Fi card that supports the 802.11a, g and Draft N wireless standards. Draft N makes use of multiple input, multiple output (MIMO) technology, which reduces signal interference and provides greater range and throughput, up to a theoretical maximum bandwidth of 300Mbps.

Bluetooth is also standard on many laptops, though some configurations provide it only as an option. For maximum compatibility with other Bluetooth devices, make sure your laptop supports Bluetooth 2.1 + Enhanced Data Rate (EDR). If you want to be able to get online when you’re out of range of any Wi-Fi networks, look for notebooks that can be configured with a built-in WWAN module, which lets you tap into a cellular mobile broadband networks from Verizon, Sprint, or AT&T for a monthly fee.

DISPLAY

Tablet PC screens can be as small as 8.9 inches or as large as 14.1 inches. The smaller the screen, the more portable the system will be; the trade-off is that accurately selecting menu icons and other items on an itty-bitty display can be tough. Likewise, while tablets with bigger screens require less prodding with the stylus, you may wind up with a heavy machine that isn't comfortable to use as a slate for long stretches. Go with a notebook that has a display size and system weight that strike an appropriate balance based on your needs.

Touch screens react to input from a stylus or finger only when pressure is actually applied to the screen's surface, making writing onscreen more difficult (it's natural to lift the pen at the end of strokes) and navigation less precise. Look for notebooks that feature a digitizer, which can sense when the stylus is hovering over the screen and also register different strokes based on the amount of pressure with which you write. Be aware, though, that in some systems, the digitizer may detract from the screen's overall clarity. Most tablets use displays with a wide-screen aspect ratio; avoid the few systems still fitted with square, standard-aspect displays.

Many screens now come with a reflective coating that provides a better viewing experience for movie-watching. Some people don't like the reflectivity of these glossy screens, however, and they can be especially distracting in a brightly-lit office environment; be sure to check out the display in person before you buy. If you want to use your notebook for video conferencing, opt for a system with a Webcam built in to its display bezel.

Business Laptop

2009-05-01T10:34:00.000+07:00

With their emphasis on security features, productivity performance, and straight-laced looks, business notebooks make a good choice for SMB and corporate users who like to take their data to go. Here's what you need to know to buy.

PROCESSOR

Look for a model powered by Intel's Core 2 Duo processor, which provides long battery life, strong performance, and cool running temperatures. If you're interested in an AMD-based laptop, go with one using the Vista-friendly Turion 64 CPU.

HARD DRIVE

When it comes to storage space, the more gigabytes you can get, the better— especially if you save lots of large documents and PowerPoint presentations on your PC. We’ve seen business notebooks with drives as large as 320GB, and some can even be configured with two drives. Make sure each drive has a rotational speed of at least 5,400rpm; some high-end notebooks offer desktop-caliber drives spinning at 7,200rpm, though you'll pay a premium for the speed increase.

In addition to standard hard drives, some vendors have introduced solid-state drive (SSD) options for their business notebooks. These flash-memory-based drives, which have no moveable parts, offer faster boot times, lower weight, and increased resistance to shock. This technology is currently quite expensive, however, and drive capacity is usually limited to 32GB or 64GB. Unless having the added durability and speed boost is a must, we recommend sticking with a traditional hard drive.

OPTICAL DRIVE

Look for a multiformat (DVD±RW) DVD burner, which writes to CDs as well as plus- and minus-format DVD media. The drive's write speed is a secondary consideration, and slower drives are cheaper. Some business notebooks can be configured with a high-definition Blu-ray drive, which can play compatible HD movies and write up to 50GB of data to dual-layer Blu-Ray disc. This upgrade is pricey, however.

CASE

You won’t find too many flashy-looking business notebooks—most manufacturers opt for staid black or gray cases that blend in well in a professional environment. In terms of size and weight, business notebooks span every category, from itty-bitty ultraportables weighing less than 3 pounds to hulking desktop replacements weighing more than 7 pounds. What size you choose should depend on your need for portability, but always look for a case made of magnesium and other molded-metal enclosures, which are more durable and dissipate heat better than plastic cases.

WIRELESS CONECTIVITY

Integrated Bluetooth and 802.11 wireless networking (Wi-Fi) are essential. Look for a notebook with a Wi-Fi card that supports the 802.11a, g and Draft N wireless standards.

DISPLAY

Screen sizes range widely, from 7 inches to 17 inches. The size of the display, like that of the case, should strike an appropriate balance between portability (small screen) and ease of use (large screen). For crisp text and smooth DVD or Blu-ray movie playback, go with the maximum resolution available on the screen size you choose. Most notebooks use displays with a wide-screen aspect ratio; avoid the few business systems still fitted with squarish, standard-aspect displays.

Although LCDs are still the norm, look for notebooks with displays using LED backlighting instead of the traditional fluorescent tubes, which offers less weight and increased power savings. Many screens now come with a reflective coating that provides a better viewing experience when watching movies. Some people don't like the reflectivity of these glossy screens, however, and they can be especially distracting in a brightly-lit office environment; be sure to check out a laptop's display in person before you buy.

Midsize Laptop

2009-05-01T10:29:00.000+07:00

Bigger than thin and lights, yet smaller than desktop replacements, midsize notebooks appeal to a variety of users with their wide-screen displays, configurable feature sets, and palatable starting prices. Here's what you need to know to buy.

PROCESSOR

Look for a model powered by Intel's Core 2 Duo processor, which provides long battery life, strong performance, and cool running temperatures. If you're interested in purchasing an AMD-based laptop, go with one using the Vista-friendly Turion 64 CPU. For maximum power, consider Intel's Core 2 Extreme, though it will drive up your system's price considerably..

MEMORY

Inadequate system memory can drastically reduce overall performance, so don't be frugal. 512MB is the absolute minimum requirement for running Windows Vista; if you can afford it, we recommend 2GB of DDR2 SDRAM, which will boost overall performance considerably. Also, be on the lookout for any free memory upgrades at time of purchase—many PC makers offer specials that double the amount of installed RAM.

GRAPHICS

Coupled with at least 1GB of RAM, Intel's latest GMA X3100 graphics chipset does support Windows Vista and its graphics-intensive Aero interface. If you like to play games or undertake graphic-intensive tasks such as transcoding video, go with a dedicated graphics card from ATI or nVidia. Low-end to midrange cards with 128MB or 256MB of video RAM should satisfy casual gamers and media mavens; more-demanding users should look for cards with a high-end graphics processor with at least 512MB of video RAM.

HARD DRIVE

A 100GB drive may be plenty of space for casual users, but those who have large digital media collections, play lots of advanced games, or edit digital video should opt for 250GB or more. We've seen midsize notebooks with drives as large as 320GB, and some can even be configured with two drives in a RAID Level 0, Level 1, or Level 2 configuration. Make sure each drive has a rotational speed of at least 5,400rpm; some high-end notebooks offer desktop-caliber drives spinning at 7,200rpm, though you'll pay a premium for the speed increase.

In addition to standard hard drives, some vendors have introduced solid-state drive (SSD) options.

OPTICAL DRIVE

Look for a multiformat (DVD±RW) DVD burner, which writes to CDs as well as plus- and minus-format DVD media. The drive's write speed is a secondary consideration, and slower drives are cheaper. An increasing number of midsize notebooks can be configured with a high-definition Blu-ray drive, which can play compatible HD movies and write up to 50GB of data to dual-layer Blu-Ray disc. This upgrade is pricey, however.

CASE

Occupying the space between more-portable thin-and-light notebooks and heftier desktop replacements, midsize notebooks weigh between 6 and 7 pounds. Look for a case made of magnesium and other molded-metal enclosures, which are more durable and dissipate heat better than plastic cases. You'll find plenty of midsize models with bland-looking black or gray cases, but some manufacturers offer more exciting color options and designs.

WIRELESS CONECTIVITY

Netbook

2009-05-01T10:28:00.000+07:00

With nearly every notebook manufacturer in the industry now making netbooks, choosing the right one can be tricky. On the one hand, most are very similar in terms of performance, battery life, size, and weight. On the other hand, you need to take a much closer look at the keyboard, screen, connectivity, and price than you might with a standard notebook.

PROCESSOR

Until just recently, nearly all netbooks used the 1.6GHz Intel Atom N270 processor. Intel also offers a 1.33GHz Intel Atom Z520, and now we're seeing some notebooks with the Atom N280, as well. In short, the N270 has a 1.6GHz clock speed and a 533MHz front-side bus (FSB). The N280 has a 1.66GHz clock speed and a 667MHz FSB, making it technically faster, all else (namely the 945GSE chipset) being equal. Intel is also unrolling the GN40 chipset, to be paired, eventually, with the N280. The GN40 should allow for improved graphics performance and HD playback.

MEMORY

Don't expect to get much processing help from the RAM: 1GB is the going rate for netbooks, and we don't expect that to change anytime soon. So long as most run Windows XP, they don't have to. As they adopt Windows 7, however, we'd be more apprehensive about buying a netbook with such limited memory

GRAPHICS

Nearly all netbooks offer integrated (read: slow, simple, weak) graphics acceleration, but the options do vary just a bit. While the chipsets aren't exactly linear, they basically range from about 133MHz to 800MHz speeds. The model numbers, roughly from slowest to fastest, are as follows: GMA 950 (133MHz to 400MHz), GMA X3100 (400MHz to 500MHz), GMA 945 (667MHz), and GMA X4500HD (800MHz). When choosing a netbook, remember that what you gain in graphics, you lose in battery life.

HARD DRIVE

When netbooks first hit the market, many incorporated fast, but small-capacity, solid-state drives (SSDs). Nowadays, most netbooks come with regular hard drives, which are much more affordable and offer a lot more storage. Most netbooks with regular hard drives come with 160GB of storage, but some companies try to squeeze by with just 80GB or 60GB hard drives without extending much savings to the consumer.
You should first decide whether you want to store anything on your netbook or simply use it for Web-based computing. If storage might come into play, go with the standard hard drive and don't settle for less than 160GB. But if speed is paramount and storage is a nonissue, favor the SSD, which can be as big as 40GB in current models.

CASE

By definition, netbooks are designed to be ultraportable, and almost all are. The netbook genre rose to popularity with models featuring 7-inch screens, but it has since settled into a 10.1-inch sweet spot. You can still find a couple of netbooks with 8- or 8.9-inch screens on the market, but those are the exception, not the rule. Conversely, you can also find a netbook with a 12-inch screen, which lies on the cusp of ultraportability but ultimately belongs in the netbook category because of its Atom processor.

Likewise, netbook weight remains limited to a narrow window, ranging from 2.2 to 2.8 pounds, with a few exceptions at either end of the spectrum (as low as 1.4 pounds and as heavy as 3.1 pounds).

WIRELESS CONECTIVITY

So far, netbooks don't typically offer more than 802.11a/b/g, but start looking for extra connectivity options, which promise to expand in the netbook space this year. Built-in 802.11n, mobile broadband, Wi-Max, and GPS are all coming to at least one netbook that we know of, with others sure to follow. And with the new Intel chipset, we expect to see a 720p-capable HD display and a built-in TV tuner, as well.

DISPLAY

As noted above, netbook screen sizes typically range from 8 to 10.2 inches. Because the screens are so small, many netbooks have trouble fitting in all the necessary pixels that common applications require, especially in the vertical dimension. This often results in program windows being too big to display on the screen, with no option to scroll because the software developers didn't factor in a screen so small.
Resolution problems often arise when the vertical resolution is too small or has been truncated from a standard resolution (1,024x600, for instance, instead of 1,024x768). While many vendors have upped their resolutions or created more options for users to get around this problem, others haven't addressed it, so it's important that you do your homework. Most netbooks today offer the problematic 1,024x600 standard, but a handful also offer a 1,024x768 display mode for tricky applications.

KEYBOARD

For regular notebooks, the keyboard can almost be an afterthought, but for netbooks, it could be a serious deal breaker. Nearly all netbook keyboards present challenges to type on, but some are coming around. HP is emerging as the keyboard king of netbooks. We've loved every keyboard HP has offered on a netbook: The keys are large, curved appropriately, and placed correctly, with an overall nice feel to them. On the other hand, HP's netbooks are a little more expensive, so if you end up ruling out the brand for that reason, we recommend looking at pictures of the keyboards of the netbooks you're considering before purchase and paying close attention to what our reviews have to say about them.

PORTS AND EXTRAS

With such pared-down machines, extras are everything. Forget about finding an optical drive built in, but Webcams, VGA ports, ExpressCard slots, and memory-card readers are all ripe for the taking, so long as you purchase carefully. You can even get an HDMI port if you want. You'll pay more than $600 to get them all in one system right now, but the fact that it's even possible means that more netbook makers will continue to offer these features in their new models at lower prices.
Operating System

Microsoft has given special permission to netbook makers to use the venerable Windows XP operating system in their machines instead of the newer Vista. Windows XP is less demanding to run on netbooks' limited hardware and RAM.

Note, though, that not every netbook uses a form of Windows. You'll find a handful of netbooks that use variations of Linux. (The versions of Linux are often customized by the vendor for their own line of machines.) These systems often come with very little bloatware and a simple interface for accessing the Web and your e-mail. You'll also typically be able to make VoIP calls and use instant-messaging apps easily. A few productivity applications will likely be preinstalled, as well.

PRICE

Always a moving target, prices vary considerably for netbooks. The most expensive we've seen will run you $1,499, but you can also find models as low as $249. We recommend something in the $400 to $500 range. This is where you'll find the best balance of price and performance. It's also where the majority of netbooks are priced, so you'll find the fiercest competition here.

Inkjet Printers

2009-05-01T10:22:00.000+07:00

Inkjet printers are inexpensive, but you still need to do a little research before you shop. These tips will help you buy the right one.

RESOLUTION

Resolution figures refer to the maximum number of horizontal and vertical dots a printer can lay down within a 1-inch-square space. In theory, a higher-resolution printer should produce more-detailed text and images, but manufacturers inflate these numbers for marketing purposes. That means these specs often have little or no bearing on real-world performance. If at all possible, view actual output from a printer before you decide.

PRINT SPEED

This spec measures how many pages per minute (ppm) a printer spits out. To come up with the fastest-possible speeds, some manufacturers use basic text documents at the lowest quality settings (draft mode) on plain paper. In our tests, using a printer's automatic mode for text and its photographic-paper setting for photos, we typically achieve about half the speed the manufacturer promises.

CONECTIVITY

Most printers connect to your PC via USB 2.0, but in many cases you'll have to buy the USB cable separately. For printing without a PC's help, look for a printer equipped with memory-card slots, as well as ports that allow for direct printing from supported cameras or external storage devices. Many models also support wireless printing over infrared or Bluetooth, or via Wi-Fi access points with built-in print servers.

CONSUMABLES

Before you buy, consider the cost of items such as ink and paper. Replacement ink can quickly exceed a printer's price, running anywhere from $12 to as high as $60 per cartridge. Sometimes, costlier printers are more economical in the long run because they often have higher-capacity ink tanks and separate tanks for each color. As for paper, use what the manufacturer recommends for the best results, especially for photo prints. These papers can cost anywhere from 10 cents to $2 per letter-size sheet.

Laser Printers

2009-05-01T10:21:00.000+07:00

Laser printers provide sharper text output and generally lower per-page costs than inkjet printers. Color lasers still come at a premium price, but these units can now be found for fairly reasonable prices if your printing needs include color.

COLOR OR MONOCHROME ?

With a few color laser printers now selling for less than $500, some small businesses might find a color model worth the splurge to add some extra pop to printed materials. For the most part, however, monochrome lasers are a far better value for home users and small businesses.

RESOLUTION

Print resolution refers to the maximum number of dots per inch (dpi) a printer creates, measured both horizontally and vertically. For example, a 600x600dpi laser printer is capable of printing 600 dots across by 600 dots down within a 1-inch square. A resolution of 600dpi is more than adequate for most text-printing tasks. If you're printing more-complex jobs—newsletters, for instance—consider models that print at 1,200dpi or even 2,400dpi resolution.

SPEED

This spec measures how many pages per minute (ppm) a printer pumps out. Today's laser printers should deliver more than 10ppm of text, with slightly slower speeds when printing a mixture of text and graphics. Most color lasers perform four separate passes on color printouts, so expect much slower speeds from these models. (Also, generally speaking, actual print speeds are slower than the speeds manufacturers quote.)

CONECTIVITY

Virtually all recent printers have a USB 2.0 interface. Don't worry if your system doesn't have USB 2.0—USB 1.1 is fast enough for printing, and USB 2.0 is backward-compatible. Workgroup printers that also support printing over a network connect via a standard Ethernet cable with an RJ-45 connector. For even more flexibility, some models support wireless printing, using Wi-Fi access points with built-in print servers.

Multifunction Printers

2009-05-01T10:19:00.000+07:00

Also known as all-in-ones, multifunction printers fuse an inkjet or a laser printer with a copier, a scanner, and (sometimes) a fax machine, saving you space and money. Here's how to buy one of these many-faceted devices.

FEATURES

Multifunction printers (MFPs) are the Swiss Army knives of printers. They combine copier, scanner, printer, and, in some models, fax capabilities in one unit, making them perfect for home offices and small businesses. The best models include a flatbed scanner and an automatic document feeder for walk-up scanning, faxing, and copying of multipage documents.

RESOLUTION

Print resolution refers to the maximum number of dots per inch (dpi) an MFP creates, measured both horizontally and vertically. For example, a 600x600dpi laser-based MFP lays down a 1-inch square comprising 600 dots across by 600 dots down. A resolution of 600dpi is adequate for most text-printing tasks. For more-demanding jobs, consider models that print at 1,200dpi or higher.

PRINT SPEED

This spec measures how many pages or photos per minute (ppm) an MFP can print. Large workgroups should opt for a laser model for faster output. Home offices, however, can save money by choosing an inkjet-based MFP, which should provide enough speed for a small office.

CONNECTIVITY

Some MFPs support printing over a network right out of the box. Newer MFPs feature memory-card slots, as well as ports that allow for direct printing from supported cameras or external storage devices.

17 Inch to 19 Inch LCD Monitors

2009-05-01T10:15:00.000+07:00

17- and 19-inch LCD monitors are today's mainstream models for most home and office users, delivering the best combination of affordable prices and roomy screens. Keep in mind these essentials when shopping for one.

ASPECT RATIO

Most computer monitors are moving from the standard proportion of width to height of 4-to-3 to the wider 16-to-9 format. The 16-to-9 format allows for viewing several documents at once, screening letterboxed movies, or watching high-definition television (HDTV) in wide-screen format. You can still find plenty of 17- and 19-inch monitors in the 4-to-3 format, but manufacturers are increasingly phasing out the smaller 17-inch size as larger-sized displays become cheaper to manufacture.

RESOLUTION

Higher resolution generally yields better image quality. Most 17-inch and 19-inch flat panels have a native resolution of 1,280x1,024; 19-inch wide-screen displays and a few 17-inch wide-screen displays usually feature 1,440x900 resolution. Make certain you're comfortable using an LCD at its native resolution before you buy it, because the image will be blurry if you need to scale the resolution up or down.

CONTRAST RATIO

Contrast ratio indicates the difference in light intensity between the brightest white and the darkest black. Look for a contrast ratio of at least 400-to-1 for a more dynamically detailed image. The ratio is measured in varying ways, however, so rely on such figures cautiously.

PIXEL-RESPONSE RATE

This spec, measured in milliseconds (ms), refers to how quickly a pixel can change colors. Theoretically, the lower the milliseconds, the better the monitor can handle fast-moving images. If the pixels can change quickly from black to white, you should see fewer ghosting or clipping effects (an indication that the monitor has trouble keeping up with the fast action). Manufacturers have started to market monitors with low response rates (some as low as 2ms), but you should be aware that this number isn’t based on real-world usage. Plus, manufacturers use a variety of methods to achieve the low number (such as measuring a gray-to-gray, or GTG, response time rather than black-to-white). Most current panels have GTG response rates of 8ms or less; gamers and video buffs should look for GTG response rates of 5ms or less.

LUMINANCE

Luminance, or brightness, is expressed in nits, or candelas per square meter (cd/m2). A measurement of 250cd/m2 is suitable for most productivity tasks; a higher rating is better for viewing television and movies, or for doing demanding work with color graphics.

DIGITAL VERSUS ANALOG CONNECTIONS

LCDs must convert analog signals before they can be displayed. A graphics card with Digital Visual Interface (DVI) connectivity can send the signal straight to the display in digital format—no conversion is required. Most LCDs come with an analog input (also known as a VGA or D-Sub port), some have both analog and digital interfaces, and a few are digital-only. A digital connection is best.

VIEWING ANGLE

Brightness and image colors shift if you view an LCD off-center. If at all possible, make your own observations of the panel you're considering, and remember that viewing-angle issues are increasingly noticeable the bigger a panel is.

PORTRAIT / LANDSCAPE MODES

Some LCDs pivot, letting you switch between traditional horizontal (landscape-mode) or vertical (portrait-mode) orientation. This feature can be useful for desktop publishing, Web surfing, and viewing large spreadsheets. Consider whether you'll actually use the pivot function if you have to pay extra for it, though.

ADJUSTABILITY

Ergonomics are important, so look for a monitor that enables you to adjust the height of the display to a comfortable viewing level. Also, a monitor that swivels from side to side enables you to show your screen to others, should you need to.

20 Inches or Larger LCD Monitor

2009-05-01T10:11:00.000+07:00

Large LCD monitors can boost productivity by enabling you to view multiple documents at once. Their wide-screen formats are also ideal for watching high-definition television and DVD movies.

ASPECT RATIO

LCD monitors that measure 20 inches diagonally can have an aspect ratio—a width-to-height proportion—of either 4-to-3 or 16-to-10 (although most new monitors are shifting to the wide-screen format). The standard for monitors that are 23 inches and larger is 16-to-10, which makes them ideal for watching DVD movies or high-definition television (HDTV) in wide-screen; larger monitors are also great for viewing several documents at once.

RESOLUTION

Higher resolution generally yields better image quality. Twenty-inch flat panels with a 4-to-3 aspect ratio have 1,600x1,200 native resolutions; wide-screen models typically have resolutions of 1,680x1,050 or 1,920x1,200, depending on the size and model; and 30-inchers allow you to view at 2,560x1,600. Whatever the native resolution, make certain you are comfortable using the LCD at that resolution before you buy it—the image will be blurry if you scale the resolution up or down.

CONTRAST RATIO

A contrast ratio of at least 500-to-1 will give you a more dynamically detailed image. The ratio is measured in varying ways, however, so rely on such figures cautiously.

PIXEL-RESPONSE RATE

This spec, measured in milliseconds (ms), refers to how quickly a pixel can change colors. Theoretically, the fewer the milliseconds, the better the monitor can handle fast-moving images; if the pixels can change quickly from black to white, you should see fewer ghosting or clipping effects (an indication that the monitor has trouble keeping up with the fast action). Manufacturers have begun marketing monitors with response rates as low as 2ms, but be aware that this number isn't based on real-world usage. Plus, manufacturers use a variety of methods to achieve their low numbers, such as measuring a gray-to-gray (GTG) response time rather than black-to-white. Most current panels have GTG response rates of 8ms or less; gamers and video buffs should look for GTG response rates of 5ms or less.

LUMINANCE

Luminance, or brightness, is expressed in candelas per square meter (cd/m2) or nits. A measurement of 250cd/m2 is suitable for most productivity tasks; 450cd/m2 is better for television and movies. If your work requires very accurate color reproduction, look for an even higher brightness.

DIGITAL VERSUS ANALOG CONNECTIONS

LCDs must convert analog signals to digital before they can be displayed. A graphics card with a Digital Visual Interface (DVI) port can send the signal straight to the display in digital format—no conversion is required. Most larger LCDs come with both analog and digital inputs (using the digital connection is better). Thirty-inch monitors require a DVI-D connector that supports dual-link technology to make the most of their 2,560x1,600 resolution. Some new models with multimedia support offer an HDMI connection, which can deliver digital video and audio through the same cable.

VIEWING ANGLE

Brightness and image colors shift if you view an LCD off-center. Try to get an up-close look at any panel you’re considering, and remember that viewing-angle issues become increasingly critical as panel size increases.

PORTRAIT / LANDSCAPE MODES

Some LCDs let you pivot between traditional, horizontal landscape mode and vertical portrait mode, which can be useful for desktop publishing, Web surfing, and viewing large spreadsheets. Consider whether you'll actually use the pivot function, though, before you pay extra for it.

ADJUSTABILITY

Ergonomics are important, so look for a monitor that enables you to adjust the height of the display to a comfortable viewing level. If you want to be able to show your screen to others, go for a monitor that swivels from side to side.

Graphics Cards

2009-05-01T10:07:00.000+07:00

You'll need a capable graphics board if you plan to play advanced games—but first you'll need to understand graphics technology and lingo. Here's what you need to know.

MEMORY

When it comes to graphics memory, you can never have too much, especially if you're a gamer. More RAM means better performance, improved 3D texturing, and higher display resolutions. If you're an avid gamer itching to frag opponents in Half-Life 2 or Call of Juarez, you’ll need at least 512MB. More memory allows for smoother gameplay, though casual gamers should be satisfied with 256MB.

SLOT TYPE

Both nVidia and ATI, makers of today’s top consumer graphics-processing units—the engines that drive cards—support PCI Express (PCIe) technology, which has vastly improved bandwidth over the previous graphics-card standard, AGP. If your computer is several years old, it might not have a PCIe slot; check beforehand, so you can get the right kind of card. Most graphics cards use the PCIe x16 slot, which is the longest slot and has the most lanes (or connections). If your system is very new, it might have PCIe 2.0 slots, with double the bandwidth of older PCIe slots; in that case, try to get a PCIe 2.0 card to take advantage of the extra speed, but if you can’t, older PCIe cards will work in the slot just fine.

SLI VERSUS CROSSFIRE

Hard-core gamers who want blazing frame rates don’t need to settle for just one graphics card in their PCs. nVidia’s Scalable Link Interface (SLI) and ATI’s CrossFire technologies let you link multiple cards (up to four) for supercharged performance. Some things to consider before making the multi-card jump: Make sure your motherboard supports these solutions (not all do); check that your power-supply unit has adequate wattage to power all the cards you want to use; and make sure your PC has enough space inside to accommodate both cards.

DIRECTX 10

The latest version of Microsoft's multimedia instruction set, DirectX 10 (DX10), enhances the ability of compatible graphics cards to render realistic visuals with complex shading and lighting effects. All the latest graphics cards support DX10 as well as the older DX9. Some even support the technology’s recent incremental update, DX10.1—most users, even gamers, won’t notice much difference between the two, so don’t worry if a card doesn’t support DX10.1.

CONNECTIONS

Most of today's LCD monitors have Digital Visual Interface (DVI) connections, which provide image quality superior to the standard analog VGA interface (which is also typically present). Make sure your card has a DVI connection so you can take advantage of this improvement if your monitor has DVI support. If you plan to add a 30-inch monitor, make sure your graphics card supports dual-link DVI—some large LCDs require support for this specification. If you have an HDTV you might want to use as a display, look for a graphics card with an HDMI port for transferring video and audio signals with ease.

Internal Hard Drives

2009-04-30T22:47:00.000+07:00

Internal hard drives deliver the best value for storage upgrades and data backups. These are the tech specs you need to know to buy the best drive for your desktop.

INSTALLATION

Internal hard drives are fairly easy to install. To ensure that everything goes smoothly, we recommend buying a kit-packaged drive rather than a bare drive; the latter may not include a manual, cables, or mounting hardware. Also, make sure that your desktop has an empty 3.5-inch bay, if you're adding a drive (as opposed to replacing one).

SIZE

A 120GB drive should provide plenty of storage for the average user upgrading an existing drive. Digital photographers, videographers, and gamers should opt for at least 300GB. No matter what your current needs, plan for the future and buy a bigger drive than you need right now.

INTERFACE

Most new drives employ the Serial ATA (SATA) interface, although you'll still see a few bargain models that use the ATA interface, also known as IDE. SATA, which transfers data via a serial instead of a parallel connection, is capable of transferring data at up to 150MB per second. It also uses thinner cables than ATA, allowing for better airflow inside your PC. Before you buy, make sure that your motherboard can accommodate the SATA interface. With the introduction of SATA/300, compliant drives and PCs can now support data transfers of up to 300MB per second. For even faster data transfers, the Ultra320 SCSI interface reaches rates of up to 320MB per second, but you'll need a costly interface card to install one of these drives.

ROTATIONAL SPEED

The speed at which a disk spins, measured in revolutions per minute (rpm), is directly related to how fast it can retrieve data. Spin rate is an important consideration for video editors and gamers; those who use only word processors, e-mail, and Web browsers probably won't notice the difference. Drives that spin at 5,400rpm are the least expensive, but you'll want to invest the few extra dollars and go with a 7,200rpm model. At the consumer-drive high end, a few models spin at 10,000rpm, but these costly drives max out at 300GB.

SEEK SPEED

Average seek speed, measured in milliseconds (ms), describes how fast a drive can locate data. It's not a huge consideration for most people, but if drive performance is your top priority, look for a model with a seek speed of 8.9ms or faster.

SPEED

The speed at which a hard drive spins, measured in revolutions per minute (rpm), is directly related to how fast it can retrieve data. Though many current drives spin at 5,400rpm, a drive with a spindle speed of 7,200rpm is a better choice.

BUFFER

Hard drives store frequently accessed data in their own RAM, or buffer, because this solid-state memory is faster than the drive mechanism at transferring data. The larger the buffer, the better. Look for a drive with an 8MB or 16MB buffer.

External hard Drives

2009-04-30T22:43:00.000+07:00

External hard drives enable you to add storage to your desktop or laptop without having to open the case. Here are details on the types of external drives and the specs you need to know before you shop.

FORM FACTOR

External hard drives come in many shapes and sizes, and most can also be rested vertically to save space on your desk. Some external models are small enough to fit inside your shirt pocket, but these tend to be more expensive on a per-gigabyte basis and offer less storage than more conventionally sized "desktop" external drives. Still, sheer portability makes them a great choice for shuttling data between home and the office.

POWER SOURCE

Laptop users who are constantly on the road and don't require massive storage space should invest in a bus-powered external drive. Bus-powered drives, typically compact, draw power from your computer's USB or FireWire port. Because your laptop provides the juice, these drives eliminate the need to carry a power adapter, although they do eat up battery life. Some bus-powered drives also bundle an external power adapter that you can use when a wall socket is available. Be aware that many portable USB drives require the use of two USB ports—one to deliver data, the other for power.

CAPACITY

In light of the ever-expanding appetite for large multimedia files, you should buy the largest drive you can afford. Even pocket-size drives should provide at least 80GB of storage, and you can get externals with capacities as large as 1.5TB. You do pay a price for mobility and ease of installation, however, as external drives tend to cost more than internal drives of the same capacity.

CONNECTIVITY

Typically, external drives connect to your computer via USB 2.0 or FireWire ports. FireWire now comes in two flavors—400 and 800—that correspond to their maximum data-transfer rates: 400Mbps and 800Mbps, respectively. Some drives have both USB and FireWire 400 ports (these drives are often called "dual interface"), and others support all three connections ("triple interface"). An increasing number of drives feature the speedy external Serial ATA (eSATA) interface, with a maximum transfer rate that can outpace even FireWire 800’s. External SATA drives usually require that you install a PCI card (sometimes bundled with the drive) in your desktop computer or an ExpressCard in your notebook computer in order to connect the drive, however.

NETWORKING

If you have a home network, you can opt for a network-attached-storage (NAS) drive. NAS drives provide an easy way to add storage that multiple computers can share. Some are as basic as a hard drive with an Ethernet port or built-in Wi-Fi; others provide extra USB and FireWire ports that allow you to daisy-chain additional drives to boost your overall network storage space. If a NAS drive has print-server capabilities, you can plug a printer into its USB port and send print jobs wirelessly from any computer on your network.

SPEED

The speed at which a hard drive spins, measured in revolutions per minute (rpm), is directly related to how fast it can retrieve data. Though many current external drives spin at 5,400rpm, a drive with a spindle speed of 7,200rpm is a better choice.

BUFFER

Drives temporarily store data in a memory buffer (or cache) because the device can read from the buffer faster than the drive's platter. A larger buffer can noticeably enhance drive performance. Look for a drive with an 8MB or 16MB buffer, rather than a 2MB buffer.

SOFTWARE

Many drives come with backup and recovery software to ease the archiving of files on your PC. Check each drive's software bundle for the best drive/software combo to suit your personal backup needs.

ENCLOSURES

Do-it-yourself types have another option for external storage: buying a hard drive enclosure that can house an internal drive (or drives). Because internal drives are generally cheaper than externals, this solution can save you money—even more so if you already own a disused internal drive. An enclosure that houses multiple drives can offer the ability to use Redundant Array of Inexpensive Disks (RAID) technology. With RAID, you can split data across several drives to enhance performance (RAID Level 0, or "striping"), or duplicate data on multiple drives for security (RAID Level 1, or "mirroring"). For more information, consult our guide on how to build an external hard drive.

Wi Fi Routers

2009-04-30T22:40:00.000+07:00

Wi-Fi routers wirelessly link all your PCs and other Wi-Fi-enabled devices, letting you share a single broadband connection throughout your home. Here are the specs you need to know.

SETUP

If you're planning to create a wireless network to share a broadband connection across all of your home's PCs, start with the broadband-connection hardware (typically, a cable or DSL modem). Plug the modem into your router, connect the router to your PC, configure the router via its included software, then connect to your network from additional PCs (and other devices) that have networking radios installed.

NETWORKING STANDARDS

802.11g is the current standard for home networks, having replaced the slower 802.11b standard in new equipment. 802.11g is also compatible with 802.11b, so you can use 802.11g gear with older equipment running the 802.11b standard. Another older standard, 802.11a, has speeds similar to 802.11g's and uses the 5GHz frequency for less interference, but it's incompatible with 802.11b or 802.11g and has a shorter range.

Many new 802.11g routers feature multiple input, multiple output (MIMO) technology, which reduces signal interference and provides greater range and throughput than ordinary 802.11g routers do. MIMO is also an important part of the forthcoming 802.11n standard, which is expected to be ratified later this year. So-called "Draft N" routers being sold today are based on a preliminary version of the 802.11n spec, but the latest draft is expected to be the finalized spec. Although early Draft N routers failed to deliver the boost in range and throughput the most recent standard promises, newer models, which can be upgraded via firmware to the 802.11n spec when it's ratified, are delivering impressive results.

THROUGHPUT

Throughput refers to the speed of data transfer a router can provide, measured in megabits per second (Mbps). 802.11b routers have a maximum throughput of 11Mbps, while 802.11g and 802.11a devices have a maximum throughput of 54Mbps. The upcoming 802.11n standard promises significantly higher maximum throughput (540Mbps). Note, however, that these maximum throughputs are theoretical; real-life performance will be slower and vary from one router model to the next.

RANGE

Range is the maximum distance from the router a wireless access point or networking card can receive a signal. As with maximum throughput, the range that a router manufacturer touts often doesn't correlate with what you'll observe. That's partly because obstacles such as walls can affect a router's range. If your router's signal can't reach a remote area of your network, you may need to purchase a repeater, a device that re-amplifies the signal so it can extend to distant parts of your home or office.

SECURITY

Most routers come with Wired Equivalent Privacy (WEP) encryption, which provides a first level of security but won't deter persistent security breaches. For greater security, opt for Wi-Fi Protected Access (WPA) or the newer WPA2 encryption, which provides stronger data protection and control over network access.
A router that supports Media Access Control (MAC) address filtering limits network access to specifically permitted PCs and devices. For added protection, consider a router with a built-in hardware firewall, which can protect all PCs on the network at once from outside attacks.

Internal DVD Burners

2009-04-30T22:35:00.000+07:00

DVD burners enable you to archive large amounts of data, as well as copy your movies to DVD discs. Here's what you need to know about DVD-burner formats and capabilities to make the right decision.

FORMAT

All new DVD burners employ multiformat technology that can write and rewrite data and video to DVD-R/DVD-RW and DVD+R/DVD+RW formats. DVD-R and DVD+R discs can be written to only once, but they offer high compatibility with drives and set-top DVD players. DVD+RW and DVD-RW discs can be written and erased approximately 1,000 times, but they have some compatibility problems with older players, some older drives, and even some current DVD recorders. Multiformat drives can also read, write, and rewrite CDs, as well as play DVDs. Some drives can record to DVD-RAM discs, although these models are less common and tend to cost a little more. DVD-RAM discs are used primarily for data storage and backup.

SPEED

The speed at which a drive can read, write, and rewrite a disc is measured in terms of "x." Most burners can write (or burn) DVDs at 16x, enabling you to burn a full 4.7GB disc in less than 6 minutes. Other drives on the market are rated at 18x or even 20x if 16x is not fast enough for you.

DOUBLE-LAYER SUPPORT

"Double-layer" refers to the technology that allows two recording layers to fit on a single side of a DVD, effectively doubling a disc's storage capacity from 4.7GB to 8.5GB. Though it's perfect for those who need to archive large amounts of data, double-layer burning currently maxes out at 16x speed (though 10x and below are more common), and the discs will not play in most stand-alone DVD players. Also, you'll run across two types of double-layer recording. Most double-layer drives support DVD+R double-layer, but some newer ones also support DVD-R double-layer. Look for drives that support both.

LIGHTSCRIBE AND LABELFLASH

Many drives support LightScribe or Labelflash, technologies that enable you to etch your own label or artwork on the nondata side of the disc. Write speeds of these kinds of drives are often slower, however, and you'll need to use media designed especially for them.

INTERFACE

Most optical drives still rely on an IDE interface to connect to your PC, but newer drives offer a faster Serial ATA (SATA) connection. One of the main advantages of SATA is that it uses thinner cables, facilitating airflow inside your PC's case. The thin cables are also beneficial for small-form-factor cases, because they eliminate the need for IDE's space-hogging ribbon cables.

BLU-RAY

If you find the space constraints of traditional DVDs too limiting, a Blu-ray burner might be what you need. Burners are very expensive (averaging around $500), but they enable you to burn up to 50GB of data to a single disc (25GB per side) and also let you watch high-definition movies if you have the right video equipment. If you want HD playback but don’t care about the storage, consider a more reasonably priced combo drive that combines a Blu-ray reader with a DVD burner.

External DVD Burners

2009-04-30T22:27:00.001+07:00

If you don't have a free drive bay—or just don't want to open your desktop's case—an external DVD burner is a convenient, transportable way to archive data on DVD discs.

INTERFACE

External DVD burners connect to your PC differently than internal drives do. While internal burners rely on an IDE or Serial ATA (SATA) interface to connect to your PC, external drives offer USB 2.0 or FireWire connections. Some models (labeled "dual interface") offer both USB and FireWire options.

FORMAT

All new DVD write and rewrite data and video to DVD-R/DVD-RW and DVD+R/DVD+RW formats. DVD-R and DVD+R discs can be written to only once, but they offer high compatibility with drives and set-top DVD players. DVD+RW and DVD-RW discs can be written and erased approximately 1,000 times, but they have compatibility problems with older players, some older drives, and even some current DVD recorders. Most new burners today support both +/- formats. Multiformat drives can also read, write, and rewrite CDs, as well as play DVDs. Some drives can record to DVD-RAM discs, although these models are less common. DVD-RAM discs are used primarily for data storage and backup.

DOUBLE-LAYER SUPPORT

"Double-layer" refers to the technology that allows two recording layers to fit on the single side of a DVD, effectively doubling a disc's storage capacity from 4.7GB to 8.5GB. Though it’s perfect for those who need to archive large amounts of data, double-layer burning currently maxes out at 10x speed. The discs may not play in older stand-alone DVD players, but most new players now support the technology. Also, you'll run across two types of double-layer recording. Most double-layer drives support DVD+R double-layer, but some newer ones also support DVD-R double-layer. Look for drives that support both.

LIGHTSCRIBE AND LABELFLASH

Some external drives support LightScribe or the less-popular Labelflash, technologies that enable you to etch your own label or artwork onto the nondata side of the disc. Write speeds of these drives are often slower, however, and you'll need to use more-expensive LightScribe or Labelflash media.

BLU-RAY

The next generation of DVD uses the Blu-ray format, which delivers high-definition video resolution and dramatically increased storage capabilities: 50GB of data on a single disc (25GB per side). External Blu-ray burners are starting to hit the market, but they are priced far higher than other external DVD drives. We recommend that you wait until the format gains wider acceptance (and lower prices) before buying, unless you have a specific need for that amount of storage (and have a full wallet).
