-same hard drive but a lot cheaper
-7970s perform better than 680s. and 680s perform the same as a 670
-modular power supplies are better. this one is made by superflower
-larger SSD is better than a faster SSD
In my opinion just get the WD Caviar Blue with 1TB, and the 670 gtx, the performance difference is minimal, a good 670 oc reaches the level of a stock 680 gtx, with ~100$ less, there's the gigabyte 670 windforce 3x, the msi 670 pe, the asus 670 dcii and evga 670 signature 2.
Any of those are a good option.
