hmmm, for the geforce thing, that was one thing i was wondering about, and was gonna post but wanted to do some research first. does the radeon have opengl support? or is it just an nvidia thing? cuz i AM gonna play games in linux. they may not be as high end as linux games, but they will require 3d support. and i bet that more games will come out for linux soon enough. as for 64-bit processors. some of the benchmarks i saw had good scores for games. at least the amd one's. like the amd fx's i wouldn't get one simply b/c of the high price. you can get a 32-bit now, and a 64 when you need one for the price of getting a 64 bit'll actually save money.

look at those fps's//
