Buying Guide - The CPU (Processor)

Unlike most other types of components that have a laundry list of manufacturers, the battle for the best CPU is being fought by only two main companies: AMD and Intel. Historically, Intel has been the industry leader, closely followed by the less expensive AMD. Currently, AMD is taking a beating from the recent price war with Intel, so it's products seem to be a little behind Intel's. This isn't to say AMD isn't good anymore, but I find that I get more for my money with Intel processors.

If you decide to chose an Intel processor, I recommend a Core 2 Duo Processor with at least a 1066mHz FSB (Front Side Bus) for the best performance, or a Celeron or Pentium E-series CPU for a budget PC.

There are two different packages in which you can buy processors: OEM and Retail. Retail packaging includes the processor, a heatsink, documentation, and usually a nice warranty. OEM processors are just the processor, and absolutely nothing else (maybe a 30-day warranty, if you're lucky). If you buy an OEM processor, you need to also get a heatsink for it, so keep that in mind when selecting a processor. If you're planning on using another heatsink anyway, snag the OEM version to save a few bucks.

64-bit vs. 32-bit explained

As the computing world moves into the 64-bit platform, many compatibility issues are occurring. Which program do I install? 32- or 64- bit? What's the difference? In theory, a 64-bit processor can handle more processes than the 32-bit CPUs. Put simply, this is saying the 64-bit is better at breaking down tasks and completes them faster.

Myth: I have a 64-bit processor, I need Windows XP x64 edition or Windows Vista 64-bit.

Look out! The compatibility monster just ate all your favorite programs! Check with the manufacturers of all your software before moving into the 64-bit world. Most programs will work just fine, but some won't. Find out if these programs have 64-bit editions or compatible versions, but if they don't you may be out of luck. The same goes for hardware and peripherals - find out if your printer, scanner, MP3 player, Blackberry, or anything else you plug into your PC will cause problems, then make your decision whether to go 64-bit or not.

You can still install a 32-bit operating system (and programs) on a computer with a 64-bit CPU, but it's performance will not be enhanced. In practice, if you have a 64-bit operating system, you should install the 64-bit version of programs (if available) to help the program run as fast as possible. Most 32-bit software will still run on 64-bit operating systems, but double check before you take the plunge.
