Buying a new computer is no small task. Making the right choice requires more than just knowing how fast a CPU you need or how big a hard drive you want; it helps to have a good idea of how you'll use your new computer.

Most people buy a PC to browse the Web, to check and send e-mail, and to juggle the occasional Word document or spreadsheet. Today, even the least-expensive computer will do the job for around 400 to 500 dollars.

If you have particular needs, many PC vendors allow you to customize and upgrade their base-model PCs with a mind-boggling selection of features. Require extra storage? Pick a larger hard drive. Want extra memory? Load up with more RAM. Maybe you would like to watch Blu-ray Discs or HD DVD movies? Choose an optical drive that supports your preferred format. If you're into editing digital video or managing a large database, you'll need to set your sights a little higher. Look beyond the basics for systems starting in the $1500 to $2000 range.

The gaming-PC market continues to grow at an exponential rate. Devoted gamers may spend $2500 and more on a computer to ensure that they enjoy maximum performance.
Originally the domain of niche companies producing high-end machines, the gaming-PC market is now the battleground for bigger companies craving a piece of the action. That means you'll find a larger number of capable gaming computers at cheaper prices.

Often, you can get a better deal on a larger hard drive or a superior monitor when you first order your computer. Even doubling the size of a hard drive may add very little to the cost, and upgrading to a higher-quality monitor may add only $100

Finally don't get caught up surfing price reductions: If you need a new PC now, don't wait a few months to see whether prices will drop further and whether upper-end performance will improve. Some shoppers find themselves stuck in an endless price-drop waiting game. Instead, decide when you need the system, and go for it.
