GTX660 Ti or GTX760?

HMMMM, any opinions? What does Ti even stand for?

The TI version of the gtx660 is the faster gk104 version.  The gtx 760 is comparable to the gtx670 and will out perform the 660ti

get the 760 non reference design 

i would personaly go with a Radeon 7950 for the same price. more powerfull card.

Really the 7950 and GTX 760 are about equal depending on what games you play.

More of an Nvidia guy tbh. I like their features and drivers a lot more.
