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.

A fair point.

That's pretty much my fall back plan. If I decide to go ahead with the external GPU and it doesn't work out then I can at least use the GPU in a desktop pc.
