I reinstalled windows several weeks ago in order to resolve a suspected drive error and noticed immediately afterwards that my the performance of my gaming PC in graphically intensive processes had decreased dramatically. I was observing consistent sub-30 FPS in BF4 (where I had never seen sub-60 FPS before) and regular sub-10 FPS drops in Diablo 3 (even on low settings). I attempted to diagnose the problem and realized that the GPU was consistently underclocking itself under load from the factory overclocked 1200 GHz to 870 GHZ in all intensive processes. I disabled the obvious culprits like PowerPlay and raised the power limit in Afterburner to 20% with no success. The GPU will actually compute at 1200 GHz in certain applications like Ungine Valley where I get good results, but in benchmarks like 3DMark the GPU underclocks and I receive significantly decreased graphic results (http://www.3dmark.com/fs/4476210 vs http://www.3dmark.com/fs/3944460). I don't know why Ungine Valley would be unaffected, but I wonder if the 64 bit vs 32 bit process is involved. I don't really have any idea how to approach this problem so I would appreciate the help anyone has to offer. I am happy to provide more information if it would be helpful.
Here are two screenshots taken immediately after I tab out of the 3DMark benchmark: http://imgur.com/as3TvXz, http://imgur.com/4zdE6Mw
