My New TT Kandaulf Build

Any suggestions on how to improve upon this build? I know a few myself. Just wanted to see if what I thought was the same as others. It is water cooled with a TT Bigwater 760 Plus. I have 3 120mm fans (top,front,back.) 850watt Corsair PS. Other than that just ask if I missed anything.

I agree with you both. SSD Is my next step. I have it overclocked to 4.2 but with the Bigwater 760 I am scared to go any further because it gets around 49c when I am playing GW2 or Diablo 3. It is very fast at the moment with no complaints from me but I do know I need a SSD to make the OS shine.. Another ? is Windows 7 or upgrade to 8?
