Yeah I used to have a 6800GS XXX Edition and I went to a 7800GT and there wasn't a huge difference. It was there but not astounding. Going to my 7900GT from the 7800GT with the EVGA step-up was WAY more noticeable. I should have a BFG 8800GTS 640mb OC next week, so hopefully that will be a huge step-up again
