Single GPU to benefit from PCIe 3.0 ?

[XenatR]

Hi all,

will the next generation of graphics cards, such as nVidia's Kepler (GTX 780), as a single GPU, benefit from the extra bandwidth of PCIe 3.0 over 2.0?

If not, how many generations away, would you say we are to have PCIe 2.0 bottlenecking a single GPU solution?

I don't think GTX 780 will, but whatever comes after (Maxwell) very well might.
But that's just speculation on my part.

and when that time comes, presumably a current i5 SB/IB or i7 SB/IB, even overclocked to 4.5ghz+, will be a bottleneck? (i mainly game at 1680x1050)

At that resolution - yeah, very likely.
