Which GPU should I get?

[pcnewbie_78]

Its out of:

edit: changed my mind, 660 ti is not worth it.

3GB 7950 MSI OC ~ $315

Edit: considering 2GB Radeon HD 7870 OC ~ $235

Is the 7950 worth the 80$ more? Can both overclock at the same amount?

For gaming of course, ill be playing Skyrim, COD, BF3 and a mix of other games.
I have a 3570k 3.4ghz CPU and 8gb RAM if thats necessary, if you need anymore info just comment.

I have looked at the GTX 670 but it costs over 100$+ more then the 660ti and I cant really spend that much/ think its necessary. This is the same case with the 7970 card (its 120$+ more than the 660ti).

I currently use a 22" HDMI/DVI TV, 720p 1366×768 res I believe.
