No probs for me mate, saying that ive gone back to using 8.12 drivers. i havent bothered going back to 9.4 as when i did that , kept chucking me out of Cod4
Im using 2 monitors, both on the main card, both working no probs but i only use one for gaming, not both
Give it a shot, u got nowt to loose, like u say, u can always set up a profile
