If your CPU is underpowered, you may see an improvement from getting OpenCL working. I haven't taken the time to redo the benchmarking in 9.02, but in 9.0 there was no advantage to OCL on in a workstation with a Core i7 and a GT900 series GPU, nor in one with dual Xeons and dual Titan X's. But there may well have been in a computer with the Titans and the i7.
Fusion in Resolve now runs on Metal or CUDA in addition to OpenCL (not all at the same time, though, obviously!) There have been too many other things to test there so far, though, so I haven't done any performance testing on it yet. I don't know if anyone else has. Early in the beta, Fusion was terribly crashy on the GPU, but that's been largely straightened out. There may still be lingering trouble on Linux, but it's great on Windows.
You say it has no trouble seeing the 1070, but it gives you an error about not finding a compatible card. I'm not sure what you mean—in the OpenCL Preferences, does the 1070 appear in the Select drop-down, but the error appears in the Status window? If that's not it, some screenshots would help.
Fusion can be sensitive to driver versions, so changing the driver may solve the problem. If you're on the latest, step back a couple of versions and see what happens.
