Hi my gtx performs really bad in both Heaven benchmark and bf3. In bf3 i get down to 30 fps when im in smoke, but it normallt stays around 40-65 if there isnt smoke and up to 100 out of battle with open scinery. In heaven i get really bad score i get 883 or the benchmark crashes

Some time ago i got really good scores and my card was overclocked to 1306 mhz, at that time bf3 ran rly good. Never under 60 fps. But now it's shit.

My drivers are up to date and im really lost. I have a feeling that it started after i had a gtx 660 in my system and than took it out and put my old 680 in. Then it became bad. Even tho i had cleared drivers and installed the right one. Ive also tried installing windows again, nothing helps. Please help me. I never overclocked with voltage and my temps never go over 72 celcius.

Specs:
gtx 680 twin frozr 3
i5 2500k
coolermaster 850w
samsung 830 120 gb
8 gb ram 1333 (cheapest i could find)

Sorry for my bad english, please help me :)
