So I have an EVGA GTX 660ti FTW sig2 card and as much as I'd like an upgrade I can't spend a lot. I'm thinking around $250-300, but the 770 is ~400 and the 760 doesn't seem worth the $250+ from what I currently have. I was really hoping the 660ti's would come down in price considering the 760 is better and around the same price, cheaper than the card I have actually. I figured if I could get a 660ti for a decent price I could SLI (never tried SLI) and keep that for awhile. I've been watching ebay trying to get one for around $150-160. Anyone know of other places I can look to get a good deal on a used or refurbished 660ti?
