Yes, once it's supported by OSX then for Resolve this will be/should be just another GPU.
It may work fine for HD, but 4K+ may hit issues as even TB3 is not that fast when we talk about 32bit float 4K or 6K frames which travel from GPU to CPU.
3x32bit RGB at UHD 30fps is about 3GB/sec, so this is close to TB3 data layer speed. If data has to travel between CPU and GPU a lot this will be definitely a bottleneck. TB3 is "only" on PCI-E x4 gen3 bus, so this is not that lot when it comes to GPU needs.
