What the hell is an AGP slot? All I know about them is that I dont have one.

Ah, well, then that would explain why the game runs so slow on your system.

AGP is a special card slot just for high-end video cards. All the new video cards use them. In fact, I would suspect that the new GeForce4 you just bought is also an AGP card and if you don't have an AGP slot on your computer, then you can't use it.

I find it surprising that your system doesn't have an AGP slot, though. Are you sure?
