Should I buy a GTX 690 or 780ti

I have been looking at gtx 690s on ebay some brand new and some second hand wondering which one i should buy thanks

Gtx 780ti is the winner for a single card complete performance at 1080p

If you go multi monitor mode, then Gtx 690 is the deal. It's basically two Gtx 680 in SLI, so technically is not a single GPU but two GPU combined together, hence the better performance.

On resolutions less than 1920 x 1080p it offers no theoretical advantage.

You should buy the 690 if you can find it cheaper than a 780 ti for Sure.
