I have an AGP2 slot. I am assuming that this is the same as an AGP 2.0 slot, which means that I can run a video card at "4x". How much does that limit the performance of the Universal 1.5V AGP 3.0 card? Specifically, how much would running a GeForce 7800 GS on an AGP 2.0 slot limit its performance, and would this performance limitation make the differences between it and a GeForce 6800 GS negligible when running on an AGP 2.0 port? Any help would be appreciated. I'm just wondering if it would be worth getting a 7800 if I only have an AGP 2.0 port.
