Games barley ran before.  The intel iGPU is not for gaming.  Elder Scrolls online ran at about 40fps with everything off @720p.  Far Lone sails was crazy choppy.  

With the eGPU hooked up, running ESO at 2048 with everything on High, getting 51-66 fps (60hz monitor)  I feel there is some cpu bottlenecking, but it does run much better than expected for a dual-core.  Very playable.  Far: Lone Sails runs everything on high.  The RGB PSU is cool somehow.  It needs some cleanup and a case for eGPU.  It's an older GPU, it does have some coil whine, but not intolerable.  Fans don't spin too much on the Vega, it dumps a lot of heat out the top of it.

Thanks for this post! I wanted to give this a try. I'm stuck with a Late 2014 mac mini, but mine is a dual-core i5 processor. I think I will follow your instructions here to add a eGPU. But everywhere I look, there are no other eGPUs I could connect to it other than the RX Vega 56. But I can't find the RX Vega 56 available for purchase anywhere haha

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
