You can change the following things in your build:
1.Raptors are overpriced.Get Samsung Spinpoint F3 500GB for much cheaper.
Very nice drives and fast too. Another option:WD Caviar Blue/Black 500GB.
2.Get Corsair 850HX instead of TT 1000w.
3.Ditch that GPU for sure.
Get single 5850/5870 for now.Add another down the road and enjoy better performance for much lower power consumption.
DX11 is a plus too!
