No dice.

Guess they've messed up somewhere. FC3 still no go, 3d mark still locks up the system. I get the feeling that they've messed up the portion regarding x79 and cross/tri/quad fire with 79xx series. ( which produces lockups in tons of games, then they actually acknowledged the problem, and fixed it in 13.1 I believe, maybe something needs tweaking again).

X79 and dual 7-series here, no issue to report. I don't have FC3 installed, however. You can find a tonne of my benchmarks in 3DMark in the pertinent thread, both single and dual card. I suspect some other issue, either hardware or software, might be afoot here.
