Crysis is a tough title, as it scales very poorly no matter what graphics card or cards you have; but at the same time you can only dream of 60 or 100 FPS at some of the higher resolutions.

Not even three GTX 280 cards are going to give you a cool performance number and we've learned that on a mainstream quad-core Radeon HD 4870 can score 30.5FPS at 1920x1200. Unfortunately, this is the resolution without FSAA and Aniso, and if you really want to push it with 8X FSAA you will score a quite acceptable 27.90 FPS. With this game this is considered a great score.

Radeon 4850 scores 25 FPS at 1920x1200 with no FSAA and Aniso, and 21.7 FPS with 1920x1200 with 8X FSAA on.

It is interesting to point out that with the current driver Geforce 9800GTX scores 18.6 FPS at 1920x1200 with no AA and 11.9 FPS at 1920x1200 8X FSAA.
