that's makes sense; I figured at the time however that being a quad would negate that speed difference, but it didn't.
I put my E8400 back in, and even at stock 3GHZ I went from an average of 35fps to 42 fps with the same settings. Roughly a 20% improvement. I seriously would not have thought that 500mhz and 2MB's more of l2 cache would make that big of a difference, but -live and learn.
Now I'm thinking that a nice i7-860 or maybe an i5-760 would be a nice bump; I'm trying to wait till next spring, but the tech bug is biting pretty hard
