Radeon pro is great. It's exactly what amd is missing. I was getting pretty disappointed in myself for switching from nVidia after so long since amd is incomprehensibly lacking automatic profile switching for games. The CCC is just woefully inadequate. It hardly has any options even I if I do want to manually switch options.
It does allow you to enable/disable morphological aa and tons of other settings that should be but aren't in the CCC settings. I don't get any unsigned driver problems in windows 7 x64, so you should be good. It's kept up to date too, it seems. It was last updated on the 9th of February.
