What problems have you been having? Just curious. I have only had them in a while, but I don't play any OpenGL games I guess so the OpenGL issue just isn't one for me.
I picked up a little benchmarking speed, but noticed something "funny" in Max Payne. I decided to try it totally maxed on resolution and while there is no pausing or jerking (which would be something I am use to) the mouse is much more sensitive and everything moves too fast (not exactly like fast forward, but motion is exaggerated.). I lower it to where I usually play (1024x768x32) and its fine.
I will keep trying this driver (28.32) for a while, but may go back to the tried and true 23.11 (or maybe 23.12 since someone said its the same but with an error fix).
