13.x are the worst Catalyst ever for my 7970M: almost every game I have causes black screen & system hang (nothing works, not even CTRL+ALT+DEL) after a while also at default clock (no overclocking). I can't play anything since 13.1 for more than 10-30 mins.
Google search shows thousands of users with the same problem with this new driver family.
What a pity, they have good performances and definitely solve flickering textures in games like Skyrim...
(Tested with Catalyst 13.1, .2, .3., .4, .5, .6, .7)
