First Build - Just Checking

Hey, decided its time to get a computer that's going to last a while, and building looks to be cheaper and much more fun so here it goes. If i could just get some comments on the system, and have a check for any compatibility issues I may have missed. Also if you have any suggestions for things that might be better for the same/less price that would be great.

Uses: Gaming, running a virtual machine or 2, movies and the other usual stuff.

Case --------------------- Cooler Master CM 690 II Adv
Power Supply ---------- Corsair HX-750
Motherboard ----------- ASUS P8Z77-V PRO
Processor Intel -------- i7-3770K
Graphics Card --------- nVidia GTX 680
RAM --------------------- G.SKILL Ripjaws X 2x4Gb
Hard Drive 1 ----------- OCZ Vertex 3 120GB
Hard Drive 2 ----------- 2TB Seagate Barracuda
OS ----------------------- Windows 7 Home Prem x64
Moniter ------------------ Asus VS248H 24"W 1920x1080

Also may SLI in a year or 2, and not OC straight away, giving me time to buy extra fans etc.

The things I have looked at the least are the mobo and the moniter, really just added to match the rest, so would appreciate any thoughts on improving them.

One question I do have however, is about the motherboard, looking at the comparison, there is very little difference between the pro and the normal version, I think its along the lines of 1 USB 3.0 port and one other thing I cant remember. Am I missing something?

Thanks in advance for all comments.

EDIT: One other thing, is the PSU giving enough headroom for 2 680's in SLI
