Unreal Tournament 3 produced very similar results when testing with both the ASUS Crosshair II Formula and M3A32-MVP Deluxe. Both boards were able to render just over 100fps at 1920x1200, with the GeForce 9800 GTX graphics card. The P5Q Deluxe on the other hand was 9.5% faster than the Crosshair II Formula at 1920x1200.
In Enemy Territory: Quake Wars the ASUS Crosshair II Formula was able to match the performance of the M3A32-MVP Deluxe, with both boards managing 109fps at 1920x1200. The P5Q Deluxe on the other hand rendered an average of 130fps at the same resolution - using an Intel CPU, of course.
Interestingly, Crysis showed no difference in performance between all three motherboards. Clearly this game is not very CPU dependent, but rather relies primarily on the graphics card for performance.
Far Cry on the other hand is very influenced by processing power, and while the Crosshair II Formula and M3A32-MVP Deluxe delivered very similar performance, the P5Q Deluxe was significantly faster.
