As far as performance per $ goes I actually think the gtx 1070 is the sweet spot currently.

If you're measuring cores per $ or GFLOP (single precision or double precision) per $ the ordering (decreasing) is the same: 1080 ti, 1080, 1070. Tesla wins on GFLOP (double precision) per $. At least according to current lowest newegg prices. It is all quite close though.
