Its a good setup, though I would consider and change some items.
I would change out the CM750W for a Corsair unit for a HX750 or 850, depending if you've got dual video card setup in mind for later on. Also I recommend the HX series for easier cable management due to them being a modular unit
Talking about dual video cards, if you want that to happen then your better off going with an ATI card instead of an NVidia card as you can't do SLI on an amd motherboard, you can only CrossFire. I would suggest getting a 5870, I would go with XFX as they have a double lifetime warranty and great customer service.
Also don't forget a cpu cooler, like Cooler Master's Hyper 212 Plus. It's an excellent 1 fan cpu cooler for $30 and for $10 more you can add a 2nd fan for a push/pull setup.
Everything else looks good, good luck with your build
