Your build is reasonable.

My comments:

1. For gaming, save $100 and buy the 3570K instead. Few games use more than 2-3 cores so the extra hyperthreads are largely irrelevant.

2. With your budget, I would build using a SSD for the os and a conventional hard drive for overflow.
120gb is enough for the os and a handful of games. With 180gb or 240gb, you may not need a hard drive at all.
My preferred brands are Intel and Samsung.

3. No game uses more than 2-3gb, so 8gb is sufficient. But, ram is cheap, and 16gb is OK. It is better to get 16gb in the form of a 2 x 8gb kit which is easier for a motherboard to manage. Good pick on low profile ram.

4. I think the sabretooth motherboards are overpriced. Virtually any Z77 based motherboard will do the job as well at half the price.

5. Buy a $30 tower type cpu cooler up front like the cm hyper121 or Xigmatek. It will run quieter and cooler. It is much easier for the first time builder to install than the intel pushpin cooler.

6. Corsair makes good psu's. A gtx660ti is very efficient and needs only 430w. Even a GTX690 needs only 620w.
