Interestingly, when testing with Unreal Tournament 3 the Asus Maximus II Formula, which is of course the gaming P45 motherboard, is slightly slower than the original P5Q Deluxe.
Enemy Territory Quake Wars shows again the Maximus II Formula to be slightly slower than the P5Q Deluxe, which is a little disappointing.
The Asus Maximus II Formula was able to match the performance of the P5Q Deluxe when testing with Crysis. That said, Crysis is known to be far more GPU dependent than CPU/Memory dependent, so this could explain the competitive results.
Far Cry is certainly not GPU bound, and as a result we find once again that the Asus Maximus II Formula is a little bit slower than the P5Q Deluxe.
