So essentially with an eGPU, you have a system similar to a Mac Pro. The cost of the eGPU project (Akitio Node TB3 + AMD RX-580) is the same as the cost of a used Mac Pro 5,1 with a RX 580. You just need to have applications that support the eGPU. You can then keep the eGPU when you migrate towards any newer Mac that has TB3 and use it with the newer Macs with faster results (thanks to the TB3 ports), be it laptop or desktop. Then just run the script to patch the mac to use an eGPU and then run another script to shadow the video from the eGPU through an iGPU if you plan to use through an HDMI connector on your Mac Mini or use the laptop screen with Macbooks. It's an interim step if you are to use an Akitio Node box, which is a full length TB3 GPU enclosure that supports the beefiest GPU money can buy and the most Mac compatible. I had been doing some feasibility studies myself and found that the eGPU is actually very feasible at least for me and can be for you. I hope this is not too late to answer your question as the question was never answered.
