Any dx10 or 11 game gives me 10-12 fps in gameplay or heaven benchmark

[kizit00]

Whenever I play any directx 10/11 games i get 10-12 fps. When I play dx9 I get 90+ FPS. Same thing happens when I benchmark with uniginen heaven. I get 10-12 fps on dx 10/11 and 90+fps on dx 9. I have the latest drivers and have even used driver sweeper to make sure i didnt have any remnants of old drivers before installing new ones. I have windows 7 64 bit which automatically comes with Dx 11. Ive tried reinstalling directx 11 with the dx websetup tool from microsoft's website and everytime it just tells me its already up to date. Does anyone have any ideas why I get such bad performance with dx 10/11? It's really frustrating. Any help would be greatly appreciated. Below are my system specs:


AMD phenom II x6 1055T @ 3.8 ghz
Asus M4N98TD Evo mobo
8GB G. Skill Ripjaws 1600mhz ddr3
Msi Hawk Talon attack Gtx 460 SLI (issue was happening even before I SLI'ed)
kingwin 1000watt mach1 psu
Windows 7 64 bit

Have you actually tested with any games? I don't like, nor trust most "benchmarking" software as it's not always accurate and can be manipulated.
