Probably not with an OC'd 8800GT. But wait a few days for the dust to settle and more comprehensive reviews to come out. The AA and AF performance at high res for the 4850 has seemed spectacular in a lot of the reviews in comparison to the 9800GTX so if you're in need of high res + AA + AF or have a CF board and are thinking about it, then wait a few days (im sure by June 25th, all the info will be spilled) and make your decision. Besides, prices are only likely to go down so it'll be a win-win
