Your right. How much time you think we have until we really need PCI-e?
I'm hoping the next gen of cards will be able to take advantage of a good chunk of the pci-e bus, but i dont think they will. It just seems like a waste to not be using it all. I guess time will tell...
Well, back to original point of my post; I splurged and got two eVGA 7900 GTX 512mB cards, and am running them in SLI. They fit, but just barely. The fan and heatsink of one card is just barely not touching the other card, and because of the lack of air space, that card runs about 7-10 C hotter.
However, it does give me decent performance with Oblivion, which is why I got the dual 7900's in the first place.
