Diablo III, Half-Life 2, Portal, Pillars of Eternity. I couldn't use my go-to benchmark game, Overwatch, since there's no Mac version (a slight from Blizzard that I'm still sore about), but I did have plenty of other games to try out. I popped open the Activity Monitor app and displayed the GPU History window and saw that what I was doing (mostly poking around on the internet and checking emails), wasn't intensive enough to even ping Core X. There was a brief whir of the case fan when I flipped on the power, but that was it. What first surprised me about the Core X was how it didn't seem to do much of anything at first. I set things up so that all apps ran through the Core X because I wanted that sweet, sweet, accelerated life. Download the script, run it in Terminal, and then set the options accordingly (he has a handy explainer on his GitHub page). It's handy, it works, and you might take a slight performance hit, but the performance boost you'll see overall more than makes up for it. You can do it for all programs, or just select programs. What I found was a handy open source script by mayankk2308 called set-eGPU that lets you do just that, set macOS to use an external GPU instead of the onboard GPU and then set it back again. Once I got over that disappointment, I went searching for an alternative that would let me loop the input/output from my MacBook, to the Core X, then to the internal monitor. There really should be, but this is one of the rare instances where Apple has gotten ahead of market tech. What I really want is a way to stream the output directly to my LG 4k monitor, but sadly there is no such beast that will accept the output from the card in the Core X to the USB C Thunderbolt on the monitor.

Then it's just a matter of plugging it in and figuring out how to hook up your Mac to utilize the Core X.
