I am about to build a PC and was waiting for Nvidia to release the mid range card from the new 7-- series lineup now I know generally it's a dumb idea to buy the latest and greatest but I really want the community's opinion on this one, should I go with 2-way SLI EVGA GTX 660 Ti or should I go with two new EVGA GTX 760s in 2-way SLI? Also what benefit does Ti really have?
