Multiple GPUs

Q: Does adding an older GT730 to my GTX 1070 (both CUDA) improve the performance?

Multi GPUs are supported, but DepthMap is still not fully optimized. Support for multiple GPUs is useful, if you want to utilize older graphics cards like two GT730.

If you have 2 graphic cards, both will be used but the work is split equally between them, so if you have 2 very different configurations it could also decrease the overall performance.

So your GTX 1070 alone is good enough. Adding the older GPU will not speed up rebuilding.
