Crysis is probably the de facto benchmark game since almost no currently available card can offer acceptable frame rates with very high quality settings enabled.

At 1280x1024 and with high quality settings on, the XFX HD4770 was very fast at 41.00FPS, matching the performance of the Nvidia's GTX260 solution:

Enabling the "Very High Details" makes the game more demanding for all the graphics cards. Here, the XFX HD4770 is still slightly faster than the 9600GT, 9800GT and HD4850 solutions, with an average FPS of 17.

The HD4770 managed to stay close to the HD4850 series even at the resolutions of 1680 x 1050 and 1920 x 1200.
