I have MB Asus P8Z68-V/GEN3 CPU I7 2600k GC GTX 670 SLI.
I saw here yesterday in Invidia controlpanel that it runs in Pcie 2.0 x8
How can that be, and can i change it? and if, how do i do that?

If you want to see more about the performance difference between PCI-E versions, Techpowerup tested PCI Express scaling using a HD 7970 and a GTX 680:

3.0 and 2.0 X16 or X8 has no difference, no performance difference at all, just added BIOS features which give no benefit to performance.

i have looked abit and was wondering if my MB supports the new 4th gen intel cpu's? like the Intel® Core™ i7-4790 Processor
Or is it totally money out of the window if i buy such a cpu?
