well dont know, mine is overclocked like a mofo. i know i was not getting those kind of frame rates on my old pentium d COD4 is always easy to run. maxed it out on my 8500gt.
Nah, its weaker than his HD 4850, however the FPS increase is probably from Phillbar's OC and the fact that the games are pretty CPU dependent and that COH and Crysis are TWIWMTBP games
But I think you won this war, you should borrow his HD 4850 and show him what the comparison would be like
