with this build I can get another gtx 780 and connect it to the other GTX 780? my monitor is 1080p and 60hz I can have more than 60 FPS? http://pcpartpicker.com/p/sBzYQ7
The motherboard supports it, the cpu is plenty strong enough, but I don't think I trust that psu to run two 780s. Especially not if you will overclocking too. I recommend getting at least 850w.
