AMD
Although I've said this a few times, I dont think anyone wants to listen to me... If you go AMD, it needs to be a Thunderbird, and an AMD 760 chipset, NOT the 750 chipset or a Via. Asus makes a great board with the 760 that has DDR memory (twice as fast) a 266mhz bus speed (twice as fast as ANY pentium 3) and 100ata hard drive support. Go for at least a 900mhz CPU and you can get 256mb ram at Crucial for $100. That board holds 1 Ghz of RAM! Fat! check out pricewatch.com
