I would say so, even though I went with the 7950
Ditto. Also get the card that is going to last you longer if you do not like to upgrade often. If you play games that are not vram intensive you should be fine. Otherwise the 3 gb on the 7950 is a bargain. Not to mention except for the one review up above almost all other reviews have the 7950 ahead of the 660ti with max settings in game especially now that the 7950 can be bad for the same if not cheaper plus 1 gb vram more also.
Do not get me wrong 660ti is a very good card but the 7950 is the best value for what you get for the $ paid though. And I have almost always used Nvidia from a 560ti to a 570 and now my 7950.
