I am looking forward to buy a graphic card. I have budget around 200-210$ (13000rs) In that range I have selected two cards - MSI twin Frozr Gtx 750 TI and nvidia Gtx 660 (not Ti). Which is one is better and why? Gtx 660 supports 2 way SLI where MSI TF Gtx 750 Ti does not. Combining two cards make a lot of difference? Really confused which one to buy >.<
