I'm looking at buying a new PC now, but had a couple of questions about my future upgrade path.
The PC I'm looking at has a NVIDIA nForce 680i SLI motherboard in it. Does anyone know if these motherboards support PCI 2.0? Also are these motherboards likely to support the G92's when they come out?
If the motherboard doesn't do PCI 2.0, but would support a G92, what sort of impact would that have on performance?
These mobos don't support PCI-E 2.0. However, they will support G92 as PCI-E 2.0 will be backwards compatible. You may take a hit on performance, but I doubt it will be too big, if any, as the bandwidth provided by PCI-E will be enough for good performance.
I don't believe there are any motherboards available that offer PCIE 2.0
Your motherboard will support G92 although, because it will be backwards compatible, which is quite nice.
The only impact on performance I can see by using 1.1 instead of 2.0 is you might not get the full performance out of your G92 GPU, it'll certainly still be faster than any other card available. But, most cards still don't use all the bandwidth of PCIE 1.1, so G92 might not use it all either.
