Just want to be sure I can SLI them. I don't see why not being that they both are the same card just different brands. Would my 750 PSU be able to handle it?

Brand is no issue when crossfiring cards, any 680 will work with any 680 :) 

Gtx 680s are very good when it comes to power consumption, so as DM said, yes, 750w will handle them quite well.

*Have fun with your cards mate, I wish I picked one up before they sold out

You can SLI, but in my opinion it is a waste, lol. The single 680 should be able to handle just about anything thrown at it!

The thing is that I already have the EVGA GTX 680 installed and I have the MSI sitting in it's box in my room. Was thinking about selling it but now I might keep it but just wanted to make sure if I plan on keeping it or not.

For a system using two GeForce GTX 680 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 750 Watt or greater power supply that has a combined +12 Volt continuous current rating of 53 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

The Corsair Professional Series HX750W (CMPSU-750HX), with its combined +12 Volt continuous current rating of 62 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with two GeForce GTX 680 in 2-way SLI mode.

That's the same PSU I have so I'm good to go.

What resolution do you run at?

1080p I know it's overkill and I can run anything on a single 680 with that res but I might consider 3 screens if i keep it.

Ya, it would be good for 3 screens, maybe somewhat useful for 120hz/3D, but for a 1080p at 60hz, that's going to be extremely overkill.
