Well to be honest, a Q9550 processor isn't bad at all but Crysis depends far more on your graphics card more than anything else. Also, an HD 5970, the fastest desktop graphics card available, cannot play Crysis at 1920 x 1200 resolution Very High with anything higher than 2x AA.
I beg to differ my friend. You do get 30 fps @1900 X 1200, on an average with the 5870, with everything turned to max. Even the 5850 manages a respectable 25-26 frames (which is quite playable for Crysis). The 5970, on the other hand, handles 1200p extremely well.http://www.tomshardware.com/reviews/radeon-hd-5970,2474-8.html
