I'm curious if anyone has hooked an eGPU up to the new macbook air. I'm not looking for miracle gaming, but for when the machine is docked for it to support dual 4K monitors in true 4k or a large 5k. Having slightly higher graphics settings on a game here or there is a bonus, but I'm talking more about raw desktop graphics performance. One reason I'm curious about this is that I'm hopeful an ARM based macbook is on the 18 month horizon. And it would be nice to get stronger graphics capability when docked now, that can also be leveraged by a follow-on machine. Edit: I found 9to5mac demonstrates an epu with the new macbook air, but they do it more from a docking convenience of a single usb-c: I actually think there's a lot to this, given how much discussion has gone on here regarding dongles.
