Yes, already tried them and they perform a bit better, but performance under Windows 7 was muuuch better! Have you tried the gpu with Windows 7? And if you deactivate Power Play is your performance thaaat bad, too?

As soon as I deactivate Power Play in the CCC the performance drops like shit! Is this normal? Only about 1/4 of the performance with PP enabled!

No one else here using Windows 8? Or is it a specific problem of my system? It's really annoying to see this nice card perform almost like my old 460GTX... :/

Good idea... But no difference at all... Does maybe anyone else here use Win8 without performance issues?

I've installed my new 7970 on a Windows 7 system first with ne modded driver from the start post. Everything worked fine and GPU performed as expected. Now I've installed Windows 8 and I'm using the latest 12.10 catalyst driver. The video performance is about 50% of my Win7 system. Anyone else expecting these issuses? Haven't tried the modded driver under Win8 yet, since I don't want to "mess" my new system...
