if you want awsome performance and a amd chip grab a amd64 FX-55 card. Its a great processor and it should fit all your needs for the next couple yrs. also to retouch on what moe said, definatly get the s939, unless your on a tight budget, then id get a septeron64, the 3400+ one only costs like 120$, but it is a s-754, and wont be very upgradable, i have a amd64 3000+ and i love it, its blazing fast and was easily installed, it also runs very nice. If you really want, you could get a intel chip, but i wouldnt recommend it, amd chips are much beter at this point. Really whatever amd card you get you will be happy with it, my amd t-bird 1500+ runs prety much any recent game with my freinds 6200 in it. Its about 5 yrs old, and im still happy with it....
