The sad part is, that is overclocked
Maybe I just need a new setup altogether at this point.
I'm gonna try and squeeze some more speed out of it but every time I cranked up the FSB any more it bluescreened.
Also, what kind of cooler do you have on that 7900 card? when was the last tiem you cleaned it? Are you stress testing it? What are your temperatures?
Stress test with Furmark/Kombustor/ or ATI tool
Temperature monitors can be CPUID Hwmonitor.
