Been looking at these:

To add a nVidia GPU to my iMac (with has a AMD m395x) for the CUDA cores to speed up NeatVideo.
From my understanding, for the eGPU to work, the application has to be running on the monitor connected to the external eGPU, however apps like Resolve etc can use the eGPU, but run on another.
Wondered if anyone has tried one?
