My video driver has started crashing with this patch (you know the one where windows takes a turd and then says "Your ATI driver crashed but has now recovered...but your game is screwed"). I'm running two HD 6970 in crossfire with AMD 11.12 driver and latest cap.
That's odd...it may have something to do with Crossfire. I'm running 11.12, the latest patch, and a single 6970--played for 3+ hours tonight with no issues.
From what I understand, the 12.1 preview drivers contains a few performance fixes for Skyrim when using Crossfire that aren't in 11.12. I normally don't recommend using preview drivers, but in your case I'd suggest trying them and seeing if that fixes your issue.
Edit: Forgot the http://support.amd.com/us/kbarticles/Pages/Catalyst121Previewdriver.aspx. Derp!
