i can get a 6800 ultra for 260 USD i can also get a 7800 GT (not the GTX) for 325 USD. which one do you guys think i should get??? Both are very tempting. What do you think is better bang for buck? the 7800GT is 65 more than the 6800 ultra. debating on which one to get. and i'm looking for BANG FOR BUCK here. NOt what is best for future proofing.
