I stepped up from an EVGA GTX 470 to a 580 in my secondary system. However, I have not noticed that much of a performance increase in my games
I'm wondering if it is my slower CPU that could be holding me back. I have a Core i7 920 running at 3.07GHz. I thought this would be more than enough, but it looks like this is not the case. I get P5710 in 3DMark '11 and P28460 in 3DMark Vantage. My games run well, but not as well as I had hoped. I thought the GTX 580 would be WAY faster than a GTX 470. Maybe my expectations were too high?
