Couple of suggestions: Get the Extreme4. It OCs better, and you get 8GB free RAM.
CM PSUs are fairly crappy; get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371049&name=Power-Supplies
Vertex4 is $10 cheaper and faster.
Get the 212 Evo.
I'd suggest a 7970, especially if getting a 1440p screen or 5760x1080. It does well at high-res.
That should keep it at much the same price point or cheaper.
EDIT: Missed everyone else!
