That will get ya about 1,041 fps in the Guru3D test Suite
Drop to twin 570's (Corsair A850 PSU) and ya lose 16% in fps to 873 fps .... but ya save $560 (GFX) and $90 on the PSU
Drop to twin 900 MHz 560 Ti's (Corsair A850 PSU) and ya lose 17% in fps to 862 fps .... but ya save $740 (GFX) and $90 on the PSU .
I find the case worth the $140 premium over the next ones I'd choose (DF-85, 1200 v3, HAF-X) but thats an area where ya can easily drop a good bit off the bill.
