How much difference does a video card make? Right now I have a dell dimension 2400 with a BFG PCI (not express) GeForce FX 5500 video card. (sorry it's the best my computer will take) The only reason I have a video card in the first place is cause some friends of mine got me hooked on Generals Zero Hour. My video card kicks me out of the game frequently so I'm in the process of building a new one. The video card I'm looking at is the XFX GF6800XT. How much of an improvement is it?
