Yes, but even Ti's getting ~1450mhz which most can hit or get extremely close to are only ~100 or so points behind. That is what somewhere in region of 5%?
It is a very large price, for what is not all that large a gain in performance (in that bench).
My 980 Ti's can hit 1560/2102 or better on that bench and are no match for 1080.
Don't forget to compare graphics scores.
