I'm sorry i have no help, but can second the experience. Just-purchased HD-6850, cleaned previous drivers out well, I installed Catalyst 11.11 with appropriate driver and running WoW led to a black screen and reboot within moments of login. Uninstalled thoroughly, installed just the 11.11 display driver from AMD/ATI, I still get random BSOD's and display drivers ceasing to work.
Letting Win7 automatically install its driver of choice seemed to put a halt to the BSOD's and reboots, but there are still oddities and driver crashes going from FS to windowed mode, windowed FS mode pops up and obscures the desktop when alt-tabbing between other things. Plus I'd like to be able to monitor temps with CCC, but installing that seems to be a one-way ticket to crashville.
Your experience tells me maybe I should try an older driver, this being my first ATI card in years I've got no experience of it working properly (and CCC appears to be the same exact buggy garbage it was years ago).
update: 11.10 was the previous version for you I believe but that was just as broken for me, in fact upon launching WoW the fan spun up to 100% before the system crashed.
I seem to have found "stability" in WoW and elsewhere (as long as I don't go fullscreen) with the original CCC & driver that came on the CD with my Gigabyte HD-6850. It appears to be version 10.9 and this old version of CCC is infinitely less irritating than the modern Vision software.
Beginning to doubt that upgrading drivers with ATI is worth it when nothing's broken, at least in my case. So much for conventional wisdom.
