gtx 650 ti problems

[ownagemaster]

hello, i have a problem with my computer that i have already tried to troubleshoot quite a few times.

here are my specs
AMD FX(tm) 4100 (4 cores @ 3.6ghz)
8gb ram
GTX 650 Ti

i have already RMA'd the card which did not solve the issue (to my surprise). i get vey low fps on multiple games along with FPS spikes and mini freezes/screen skipping. I still have my old 8600 gts which i tried that although it doesnt match my 650 in performance, is much more stable and less buggy. what could be the cause of this? (while playing marvel heroes, i found that turning my speakers off reduced the skipping, although this might be anecdotal at best)

Temps for CPU and GPU? You have enough power? Updated bios and/or motherboard drivers? (Including audio.) Might want to also look into core parking and maybe affinity assignment.

my CPU temp doesnt exceed 45 celcius while my GPU tends to hover around 35 celcius which seems to be fine. drivers are up to date and i have already tinkered with all combinations possible of affinities while playing diablo 3 which gave no results =/ i really have no idea why this is happening. could this be a CPU bottleneck? malware? physical dysfunction?

edit : i have a 600 watts psu

i have no idea what could be causing this... im my only option to change my cpu?

Update bios? A real 600W? (650 boost doesn't use a ton of power but if you have something REALLY crappy...) What CPU and GPU load are you seeing while gaming?
