I want to change my crappy 6200TC with something better now i have the time to play. I'm gonna play at 1280x1024 and like lots of AA and AF. I'm thinking of a 1900xt, but dunno if it's going to be a little over kill for my system (AMD 64 3400+, 1Gig DDR 400). Would be better to buy a 1800xt? The difference in price is 100€.
