Is there any advantage to running an Nvidia GeForce GTX 670 graphics card that is built for PCI Express 3.0 on a motherboard with PCI Express 2.0 x 16 slots? Would a PCI Express 3.0 capable card be any faster than using say, a GeForce GTX 570, due to the PCI Express 2.0 throughput limitations?

No, the difference is 1 percent at best, wthin margin of error. PCI-e 1 16x, PCI-e 2 8x, and PCI-e 3 4x are all adequate right now for single card solutions. When SLI/CF gets thrown into the mix that's when these bandwidths get saturated. Also what brand is your PSU?

I'm trying to avoid spending more on a newer card if I don't get real benefit over an older version. either will be considerable fater than the GTX 260 I'm currently running.

So, you're saying there would be no advantage to using a newer PCI Express 3.0 compatible GeForce GTX 670 vs the older PCI Express 2.0 compatible GeForce GTX 570 on a motherboard with only PCI Express 2.0 slots...
or...
are you saying the newer, faster, more power efficient GTX 670 card will only run slightly slower than it's rated spec even though it is in 2.0 slots? I need to upgrade my graphics card soon due to Premiere Pro CS6 upgrade so any OTB advice would be helpful.

BTW: It's an HP Pavilion Elite e9290f Desktop and the PSU manufacturer is not in the specs. I will need to open it up to take a look.

Thanks

Hi KMartin I think he is trying to tell you that you will not notice the difference between a PCIE 2.0 slot and a PCIE 3.0 slot.

The 670 is the better performing card on both PCIE platforms.
