Wait, what? I was under the impression it was just TB3 from MBP to eGPU and same from that to monitor? If I can drive it from the laptop what is different?

Ok, not sure if I'm getting confused - but you are talking a MacBook Air and/or a MacBook Pro, the LG UltraFine 5K display, and an eGPU enclosure and GPU to fit, right? The only eGPU/GPU that can directly power the LG Ultrafine is the Blackmagic one as the 5K display is unique in the way it combines 2 x Display port signals into one TB3 connection. No GPU's come with TB3 connections. However... if you Apple I on an App you get a tick box in the info panel that sets "prefer external GPU" but you will lose some performance through bandwidth.
So...
eGPU <>MBP <> LG 5k
Whereas normal screens with egpus would be...
MBP<>eGPU<>ScreenThe performance loss will be somewhere around 10%.
The real problem is buying them all in the same place as BTO Macs can't be bought in most places - maybe a Mac specialist will be able to supply?
@CYOA the new Macminis are made for you... base model with 16GB of ram and top CPU, all storage through Raid 0 Nass and a Vega 56 in a Core X or Sonnet. The latest 13inc hMBP's are also pretty punchy due to their quad core and not that far behind desktops when coupled with eGPUs.
You jokers just missed out on my spare eGPU - Sonnet and an RX570, sold for £250.

Going to have to be Amazon I think as eGPU's are not sold in many places. Also, hope you are aware you can not directly drive the LG 5K with an eGPU?
