AMD Driver List: http://support.amd.com/us/gpudownload/windows/previous/Pages/radeonaiw_vista64.aspx
Also--just to clear up some confusion that's going around...AMD royally screwed the pooch on these drivers. If you visit their downloads page, check the Steam news post about them, etc., you'll see them listed as 12.2. This is correct, since they were originally intended to be a February release. (AMD's driver numbering corresponds to the year + month released, so 12.2 is the February 2012 release. Etc.)
However, when they're installed, if you check the version number in CCC, it's listed as 12.3. This is incorrect. The "real" 12.3s, aka the March release, are still forthcoming. How or why AMD screwed this up, I can't imagine.
So, if you have these drivers installed, are having the above-mentioned issues, and need to roll back, downloading 12.2 will not fix your issue. You're just installing the same drivers over again. Drivers considered to be good and "safe" are either the 12.1 official release or the 12.2 preview. Not the pre-certifieds: they're the same as the 12.2/12.3 release, just without official WHQL certification.
Which driver works best for you will depend on your system, your card model, and whether or not you have Crossfire or a single card set-up. FWIW I'm using the official 12.1s with my single 6970, and have zero complaints.
