I do, and it’s my favorite thing about thunderbolt. I have a 2016 13-inch MBP I can easily travel with but when I’m at home (which is most of the time lately) I can use a powerful GPU which makes my Mac run cooler and let’s me run apps and games I otherwise couldn’t run well. I also have the freedom to upgrade my graphics card at any time, which you can’t do with integrated graphics.
I know I’m likely in the minority, but the lack of eGPU support for ARM Macs is really disappointing, especially after Apple spent the time to add native support for eGPUs in macOS for Intel Macs.
