i bought the new card although having a bit of trouble overclocking it , would it be my psu not enough power ? or maybe im just pushing it too far

yer im leaning towards sli with 2 gtx 580s and yer i will need a bigger psu , your probably right that i dont need to overclock i was just running crysis 2 max everything including dx11 and high res patches at 1920x1080 and was running 40-50fps
