AMD Catalyst 12.x Drivers

I see AMD released a 12.1a preview driver, has anyone tried this?  Wondering if there would be any performance differences with mining.

AMD appeared to already be silently updating the previous preview release, the version of it that I downloaded two days ago had Stream SDK 10.0.851.4 instead of 10.0.851.3. This release has 10.0.851.6. The Stream SDK/OpenCL version is what makes a difference in mining, and I doubt there will be many changes in the new 2.6 architecture (not like the huge changes from 2.5 to 2.6) now since it is not a preview, it is the current developer SDK.

Tested: Identical mining performance to previous preview.
