Whether you're s754 or s939, you can get a pci-e motherboard and a faster pci-e video card for little more than the premium you'll be paying for a faster agp video card. Particularly if you are looking at the fastest current US agp card, the 7800GS. If you can't go that route, look for the best deal you can find on a Leadtek 7600GT, an X800XT, or an X850pro.
