I Have an Asrock X79 champion, A I7-3930k at its default speed i believe (im nervous to OC it lol), and i have a EVGA ACX SC 780 ti (im going to SLI it soon).btw my gpu-z reading says its pcie 2.0 x16 and all pcie slots are pcie 3.0. going a bit more in depth i have my card placed in the 3rd pcie slot down and that should still be better with pcie 3.0 x8.
EDIT: my cpuid says im at 3.5 GHz
