660ti is better performace but no upgrade path and will need to mess around with sli.  680 you could get a second one latter and a single card is easyer to use.

GTX 680.  Less hassle because its one card and if/when you get a second one later it will perform better in SLI due to a much larger memory bandwidth.  The 660ti is limited when it comes to SLI because of its 192bit interface.  The GTX 670 is also a good choice.
