If it's not too late and you already got the board, I would suggest you actually go for a Sabertooth 990FX unless you want to go quad single GPU cards. Sabertooth has a much higher stability and reliaility rate, and it costs less. The crosshair is a gamers board made specifically for top of the line gaming systems.
That looks like a really nice board, but I think I will still go with the Crosshair V because it has a lot of nice features that I think would really help me, such as the ROG Connect and the higher number of USB 3.0 ports, and the built in sound chip that the Crosshair V has is amazing (I can't stand poor sound), and the Intel LAN is also really nice. I think that the Crosshair V is definitely worth the extra $$$.
