>The Mac Pro 2010 is the exception since you can upgrade its GPU to a Metal compatible one. You can also do this with the 2008 Mac Pro; either by using a recent nVidia GPU (though every time I've done this I've seen a bunch of weird artifacting) or by using an AMD GPU with the patch that removes the requirement for the SSE 4.2 instruction set (which the CPUs in the 3,1 don't support). RX570s and RX580s being 100 dollars makes the decision upgrade that much easier.
