More information on the kind of display device you have will also help, no use of going with 4870 with a 19" LCD, 4850 would do enough justice on a 19"
mine still lags during some instances in Crysis Warhead... ive got 8xAA, settings on Gamer mode and motion blur at the maximum... otherwise I get a constant fps of 30-40 fps....
