I'm almost 100% sure you don't have one since they have only been on the market for a few weeks.
There is no point in getting a PCI-e enabled motherboard and a PCI-e 3d card yet since the current generation of 3d cards are barly faster than there AGP 8X counter parts. I'd a couple more years and the PCI-e will be worth getting.
If I hold off til 06 to get a new comp, would PCI-Express be a good deal by then?
Possibly, since we've been sticking with standards for so long. By then, intel should be pumping out a desktop 64 bit processor, 2 GB should be standard in mst Pc's, and the newer graphics cards might be riding a high bandwidth PCI-E bus. Or a new standard, but I doubt that. AGP 8x should tide you over until then, unless you're a really hardcore gamer. wink
