Based on my iMac build.

I bought OMEN 17 notebook for gaming, so this Mac build is just a test. I will upload my OMEN build later.


ASUS RTX3080 010G gaming


Disable auto driver install and update, DDU the driver and plug the eGPU after desktop screen appears and install the latest driver manually. That worked.

I don't use Razer synapse software. I use the 1m cablematters active cable.

I have the identical iMac and Razer Core X with RTX 2070 Super, with Windows 10 2004 latest updates. Works perfectly and it was 100% plug ‘n play installation, no messing with drivers. My question is, if I upgrade to 3080, will it work just as well without any hiccups? In your opinion.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
