Hello everyone,
In case you missed it, the new Catalyst 13.8 Beta Driver is out. Note the details in the Feature Highlights section, should answer most of your questions.
And if you are looking for more information including a thorough review, check out the article by Guru3D
PS. I can't include links since I'm still a noob here, but you can dl the driver from the AMD site (support & drivers). And search the Guru3D site for the article (key word Catalyst 13.8 by date)
