I just wanted to ask some advice about my 7990 and low performace I have been playing project cars and the gpu usage only goes to about 50-60% on each core, I have a 2600k, unclocked and overclocked to 4.5GHz tested and the cpu usage is about 40-50%. The 7990 is stock speeds with LT Matt bios installed, and the fps are about 30-40. Could my power supply be holding the system back it's a corsair tx 650w.
Thanks

You might have power issues and you might not! But have a read here ... http://forum.wmdportal.com/showthre...ve-improvement..-what-s-changed-..-1-question
I was getting stupid low fps with stuttering @ 1600p, after that thread I was getting 100+ in most places on 7970/7990 with high gpu usage .... some flashing texture issues though but mostly ok.
My 7990 with overclocked 4930k was drawing around 700 watts at the wall peak so you may be ok.
