Hi there, i just brought my new sapphire HD 7770 ghz edition Oc GPU and it perform worse than the old asus eah 5670. (AC 3 for example, only 20fps on low settings ) It work only well with bioshock infinite. my psu is 500w and my motherboard is MA78lmt-US2H. Is it possible that my motherboard bios is too old? Or what would cause the problem?I have the newest drivers.
Thank you so much. ( cpu and my ram is pretty good. )

I have an amd athlon II x4 640. bioshock infinite cpu usage : 34% - 55% RAM is around 50% ( 4gb dual channel ) Wonder why bioshock working with max graphics 720p on 60 fps... thanks for supporting me btw.
