I was originally going to go with a GTX 660, but I got a great deal on this card. This is really the sweet spot in the market at this time. It performs on par or better than a GTX 670 or 7950 for much less money. Don't waste your money with the superclocked version.
Fast, fast, fast..; did I mention fast, Runs cool for performance level
Power hungry - 170W TDP; Drivers can be hit/miss; (not specific to this card; so I didn't reduce the score
