Worth "upgrading" internal 2060 to eGPU'ed 1080?

I have an Asus ZenBook Pro Duo UX581GV with GeForce RTX 2060 and i9 9980HK. 

I already have a Geforce 1080 card which is not in use. I'm considering buying an eGPU and use this card with a 4k monitor. According to gaming benchmarks, the 1080 is ~30% faster than the mobile 2060 on 4k. However, that's when used in a desktop PC.

Given that the eGPU with Thunderbolt will have a slight performance penalty -- do you think it will be worth doing this upgrade?

1. A GTX 1080 Thunderbolt 3 eGPU will not be a performance upgrade from your RTX 2060 dGPU. You'd need to upgrade to a higher performance GPU like a RTX 2080 Ti to see improvement. Consider how TB3 bandwidth limits performance:

2. Your Asus ZenBook Pro Duo UX581GV doesn't have a second M.2 slot to be able to add a higher performance M.2 eGPU:

Thanks a lot. I'll save the $$$ or consider a 2080 board then.
