Yes, it will be more than enough, a 750w would take care of your sig rig with two 580's smile.gif, so the 850w will give you some room to spare - I've personally run 2x 580's with a 850w in a previous rig (before I downgraded to what I have)

Quite enough, no worries. I would be more worried with those two massive cards fitting on the same motherboard. The bottom card might block some things.
