Very small to no difference at all comparing pciE 2.0 vs 3.0 and same with x16 vs x8. Check this out:

You're running a bit of an older motherboard, so you're actually going to run in PCIe 2.0 instead of 3.0. This might cause a bit of an issue, as it halves your bandwidth. Even then, most modern graphics cards are not bottlenecked by 4x PCIe 3.0 lanes, which is equivalent to your 8x PCIe 2.0 lanes, so you should be fine, but it's cutting it a little bit close.

That does sound like a pretty sweet deal. The 2600K is still a champ of a CPU. Good luck!
