I would have certainly preferred to do this, but it would have involved a $2000 upgrade first! (Well, barring the TB3-to-TB2 adaptor approach, but I've seen almost no builds doing this.) Also, from what I've seen, there's a lot of uncertainty regarding eGPU support with TB3; many people have reported problems on TechInferno etc., and even AKiTiO is unclear about Mac support. (If you check the specs for the Node, you'll see that Macs are listed as unsupported. Does this mean OSX-only or BootCamp as well? Who knows?) Might be worth waiting a year for things to shake out. Also, I was optimizing in part for cheapness. Truly great gaming cards cost $300 and up, and $400 total was about as much as I was willing to pay for an upgrade.

TB3 is supposed to be fully backwards compatible with TB2; it's just a different physical connector. That's why even Apple only charges $29 for the adapter. Waiting a year is way too much caution for me. I wouldn't pre-order anything, but once other people post it works I'd feel safe to proceed.

  These adapters support hooking TB2 devices to a TB3 host, but not the other way around. Intel initially announced that TB3 devices would be compatible with TB2 hosts, but it looks like they quietly dropped this feature. It's _really_ hard to find a reference on this though.

    I thought the same thing as you, but it seems that at least some TB3 devices work with TB2 hosts, e.g. the LG 5K display: https://support.apple.com/en-us/HT207448 https://support.apple.com/en-us/HT207448

    This guy[0] seems to say it works with the Razer Core. https://www.reddit.com/r/apple/comments/5l3y0a/egpu_my_experience_with_the_15_tmbp_2016_and_a_15/ https://www.reddit.com/r/apple/comments/5l3y0a/egpu_my_exper...

      Looks like I had the wrong impression. Thanks for the link!
