Will I be able to run 2xGTX 680 (details are in the thread)

I want to be able to run 2 overclocked ASUS GTX680s on this motherboard and PSU?

XFX Core Edition PRO850W:

My other question is, will I be able to run 2xGTX685s at this power supply or do I need a better one to run two GTX685. I heard that GTX685 will use 250w-300w and I know that GTX680 pulls around 185w.

Will I need extra power?

It looks likethe motherboard is ok with two Pci-e 3.0 slots with both running at x8 and the power supply is good.
As for as a GTX 685 there have been rumors but no sightings or info on requirements or performance so right now it's a ghost card untill there is something concrete that is released of leaked from someplace.
