Any of the unigine benchmarks work great. As long as you record which settings you use for each test. I just got done overclocking my 1070 using heaven and superposition.

I used greenwithenvy to do the OC itself

There's also PTS for all your benchmarking needs. https://www.phoronix-test-suite.com/
