The power requirements of the 780 is around 250W so if two of them take 500W at peak that leaves 350w for the rest of your rig. Personally I think you would be okay with that power supply.

3 monitors isn't worth it unless you play lots of racing sims/flight sims. The extra view distracts in FPS games and etc, and games render 2 monitors and stretch them across 3, so it's very odd to look at.

Get a good 4K or 1440P monitor if you're gonna get 2 SLI 780s.
