Well, right now im using a 9700 pro. Ive been looking to upgrade, and I just recently bought a new mobo (I have a 3200+, 400 fsb on a Chaintech NIL1 - mATX). Would I really see a performance boost between somthing like a x800 XT AGP, and an x800 XT PCI-E? Its looking like PCI-E is cheaper, but I would have to buy a new mobo, cpu, etc. I can also RMA this 9700 pro for a 9800 pro, but it doesnt seem like a huge boost for me.
