I'm thinking of getting a new gaming rig this weekend and was looking into SLI/XFire 670/7970. After doing my research, it seems that both these cards have more or less the same performance and scale similarly. As a result, I've decided to buy which ever is the cheapest. So far I've picked out all of my components but am unsure which motherboard I should get. I'm looking for some suggestions for both SLI 670 and XFire 7970.
I plan to overclock my CPU (I've never OCed before) and perhaps even my GPUs. I'm planning to purchase my first GPU this weekend, and the second one later next year when the prices drop. I'll be using two 27" monitors, each at 1920x1080. I'll only have the game running on my primary monitor. I primarily play online FPS.
I also want to confirm if a 750W psu is sufficient (I'm pretty sure it is), and if there are any special features the psu needs to SLI/Xfire.

I've been hearing alot of good things about the ASRock Z77 Extreme4 mobo. How is that?
