Where to start, well, a few days ago i noticed on WoW that my FPS are lower than usually so i checked my scores on Kombustor (Yeah i know its a shitty benchmark but its the only one from where i remember my scores) and the score was indeed lower (was 114 now 86). I thought that the latest AMD driver may be buged so i downgraded back to the old but still without success. Downclocked my CPU back to stock freq. but it was even lower. Today i re-installed Win7 but still without luck i did a test on 3DMark and it said that my rig should perform better (only the GPU scores were worse then they should be). Oh and i was cleaning my case could be that the issue ? And what should i do ?

My specs are:
CPU: AMD Phenom II x4 965BE OCd 3.8k
GPU: MSI R6970 Lightning OCd 1012/1495 (Did 3DMark on stock freq.)
Mobo: Asus Crosshair III Formula
Memory: Kingston KVR1333D3N9K2 4gb
PSU: Epsilon 80 Plus 700

Okay apparently i fixed the issue by simply cleaning the GPU and re-mounting it.
