That's not a gaming computer, that's a workstation.
You want to build on s1155, not s2011. It'll be A LOT cheaper and a lot faster for gaming.
What on Earth would you need a 1050w power supply for?? Even dual GTX680's only requires a 750w psu.
You haven't even told us how many monitors or what resolution.
Which is why you should fill out the new build form in the new build section of the forum.
