Just installed new drivers myself. I don't know what it is about ATI drivers, but I always have problems. Hopefully this version will fix some problems I've been having (CCC randomly crashing, screen flicking on and off). After install and reboot, the colors in my windows sidebar were all screwy and CCC crashed along with a lot of screen flicking. Rebooted again and things seem ok now. *crosses fingers*
Regardless of driver issues, my 4870x2 has been able to run anything I throw at it with ease at 1900x1080 so I'm satisfied with that. Great hardware, crappy drivers.
