Btw, can you update this thread once the problem is fixed? Because I am eventually going to upgrade to a 6800 or maybe the x800 when it come out and I wont do it until there are compatibility issues with Maya...

Also, I have read that a few user on cgtalk had no problem with the 6800 ultra so maybe the problem isnt generalised which means that its maybe not a driver issue... Or that the people reporting no problem arent using Maya with the same specs as you. Btw, try to change resolution / refresh rate, I dont think it would change anything but you never know...
