So here's what I would do: Sell the 560 Ti (with games like Crysis 3 coming out, it won't be much use to you) and I'd sell your old PSU. With that money, I would upgrade those Graphics cards to 7870's, or better yet, lose the SSD too and get two GTX 680's or 7970's. You're PC would be crazy powerful then. That's just me, besides that, great build. Also, you'd better overclock that 3570k, and if so, grab some high performance fans for the Hyper 212+.
