Anyone Using an External GPU? (quokk.au)

I have a Thinkpad T490s and would like to use an external GPU so I can power multiple monitors in High Def.

Specifically, I'm looking at the TH3P4G3 with a 5070 Ti.

From the reading I've done it seems like getting these configured and working is non-trivial. For example there's some reports of people not being able to deliver power to the laptop while docked. Also some crashes on connect / disconnect.

I'm not necessarily looking for specific "how to" advice, just a general impression. Is this worth while or is it going to be a huge muck around that never really works reliably.

So, I'm running a rando Chinese eGPU on a ThinkPad t15 gen... (Whatever an 11th Gen Intel is.) I had to spend a bit too get a nice long thunderbolt 4 cable, and I had to fart around with getting it to sleep and wake up reliably in Fedora... And my cat crashed my system totally by unplugging it mid-game in an attempt to chew on the cable. Otherwise, once I got it working, very happy with it. Had to go over all the settings when I went from Fedora 43 to 44 though. Edit: spelling.
