*Change the motherboard to Asus Extrme 4 or Gigabyte GA-Z77X-UD3H, they are better according to Tom's
*There is no point in getting a noisy HDD when you've got a SSD, buy a Samsung SpinPoint F3 instead of Caviar Black
*EVGA uses reference cooling for their GPUs so switch it to a Gigabyte GV-N670WF2-2GD, Gigabyte GV-N670OC-2GD or Asus GTX670-DC2-2GD5
*Do NOT buy roselwill's PSUs, they have a high failure rate and you do not need 850w, the PSU i linked (
this one) is a lot better and has higher manufactuiring quality (PC Power & Cooling manufactures a lot of Cosair's and XFX's PSUs)
Edit: this psu --->
http://pcpartpicker.com/part/pc-power--cooling-power-supply-ppcmk2s950 is a lot better than the one you picked and the one i recomended, if you have the extra cash buy it.
