The Optiplex GX110 was designed to be a workstation. To save space and money they used a motherboard with a built in Intel AGP video chipset.

DUH, of course, silly me. We're mostly a Dell house here where I work and I should have known that. We've got 110s here and I should have realized what he was talking about.

And regarding the PCI GeForce4: I had no idea they still made PCI cards, that's interesting. I dunno about how well it's going to perform, but hey, give it a shot.
