given the fact, I have quad sli, these betas don't work for me. #01.42 still, far and away , the best driver for quad 690 and there is plenty of room for improvement. Playing Crysis 2 at 75% capacity cuts my FPS accordingly. There are two games I'm playing now, close to 95% efficiency-Unreal Tournament 3 and Alan Wake. BF#3 has issues, I can't even loadDeus ex Revolution and Crysis and Crysis Warhead are either not loading or poor per card usage. I need a new driver that addresses multi monitor gaming on a quad!
