Yeah it looks like a pretty good build but you don' need such a powerful supply since 10 you are not running crossfire or SLI configurations and 2)everything else you have doesn't require so much power....everything else looks pretty good to me as long as you have a motherboard that will work well with your cpu you will be good to go.
Would agree, if only slightly. COnsidering the rest of the components eg Kingston RAM, Coolermaster PSU, w/e that case is.
The CPU is really nice of course. Save yourself some cash and use Windows 7 Beta till Sept and then put that extra $100 into a nice 9800GT and better brand PSU (Corsair,Antec,PC P&C) / RAM (G.Skill, OCZ, Corsair)
