2013 nMac Pro with eGPU for FCPX?

As new iMac Pros and Mac Pros appear on the horizon, wondering if there's any way to get more bang out of my now old 2013 Mac Pro trashcan.

While I know it's possible to use an eGPU over Thunderbolt 2 with the trashcan, my question is: anyone have experience with this setup? Is it working well for FCPX? If so, what card would you recommend?

Or is the whole idea just throwing away dollars for meagre improvements...

If only I knew when/how much the 2018 mac pro was, it would make things a lot easier.

Thanks!

You won't see any significant gain. TB2 isn't really fast enough to make this a reality. Wait, get a new model when they're released.
