My main concern is that the power supply may not be big enough.
I wouldn't be concerned with the PSU. It's a quality one and has lots of power. The OP could get by with a 550w quality PSU if they wanted to, he just needs 2 x 8 pin PCI-e power connectors to power the GPU. Mind you the 550w PSU would probably be on the lower side of power needs.
I just have some questions:
* Why are you spending so much? It isn't needed, IMHO. The Intel i7 3770k would be tops for 99% of people needs (I'd go with i5 3570k, but that is just me)
* Is there a real reason to go all out in price/options?
