I'm not sure if my link was working but I was using GTX 970's the entire time.Why would you need/want to bump it to a 1000W PSU when a good 650-750W can handle two of those GPU's?
Also your total is ~$4,400, with the suggestions I mentioned earlier you can get dual 970's for about $800 less.

I didn't really skimp on anything, if you wanna pay an $100 for a longer warranty on the WD Black drive that's up to you. Double the GPU power or remove one and save $500. Double the SSD capacity, all for about $1000 less.
