Thunderbolt 2, if supported natively by the hardware and using an external monitor, might actually be enough in practice. I used to game on rMBP 2015 with a GTX 1080 in a TB2-connected eGPU and it didn't even saturate the link, so when I upgraded to an iMac with TB3 the performance was pretty much identical.
The rule of thumb is: use an external monitor and the highest resolution possible. Sending control commands one way consumes much less bandwidth if you don't need to send whole images back down the link, and the high resolution and quality is to make the GPU the bottleneck, not the TB2 link.
