Not sure on what GPU to get

http://pcpartpicker.com/p/tkBp        I'm not really sure what GPU to get... I am getting this for gaming and I am on a 1,100$ budget. Any advice?

Pick a Radeon 7950 or Geforce GTX 660Ti.

Radeon comes with Sleeping Dogs, Hitman Absolution, Farcry 3

Geforce comes with Assassin's Creed 3

Both are similar in performance.

If your budget is that high, then why not get a better heat sink?

Well I'm just now kinda learning this stuff, and someone told me that it was enough... Or something like that plus I was originally going to get a GTX 670. 

7950 Is a little faster than a 670.

 That heat sink is fine btw.

Any recommendations on what type of 7950 to get? There are so many. D:

MSI Twinfrozr, Asus DirectCU2, Sapphire Turbo, HIS Turbo, whichever's cheaper I guess.
