Woah there buddy! Nice setup. I'd make a few tweaks though.
-First, where is the PSU and HDD?
-Might wanna drop the case to a $99 one, like the HAF 922 or Corsair 400R.
-Get 8GB ram. Much cheaper and you'll see the same performance.
-Drop the cooler to something like a Hyper 212+ EVO unless you plan on doing some CRAZY OCing.
-Lastly, cheaper motherboard. An ASRock P67 Gen3 Extreme4, or the Z68 Extreme3 are good options that will save you a bundle.
We'll talk more about graphics once you've looked at those changes
My bad, I was planning on going with a corsair hx850 or 1050 for the modularness(that a word?) and If I SLI I don't want to have to worry about lack of juice. I was concerned dropping back to an ASrock as I have heard lots of bad things. I really hadn't fully decided on the cooler and apparently grabbed the worng link for the ram, meant to grab the link for the 8GB kit.
