I'm having issues with my 8800GTS 512mb. I get less than half of FPS than my previous EVGA 780i and Maximus Formula X38. It's my second P5K-E, the first one used to run a 8800GT with no problems and got 15k+ on 3DMark using 602 Bios. Right now I'm using 1006. The card is fully seated and I've tried a bunch of drivers already. It crashed a few times when FPS seemed ok on 3DMark. Help please!!!
