The Sabertooth is overrated, expensive, and not worth the premiums. The Corsair GS series and Force SSD are not good choices. The 660TI is also not a good choice when the Radeon 7950 is a few dollars more and outperforms it. I wouldn't recommend a SSD or that case.
I think I'd scrap that whole build and go with something like this:
Gives you an overclockable i5 3570K with an equivalent in performance motherboard, a PSU that allows futureproofing SLI/CF, you get a 7950 that's priced better than the 660 Ti, a 128GB Samsung 830 SSD, and just overall everything you need.
