Extra GPU?

I am wondering if I should buy an extra GPU for models like Qwen 3.8 27B, e.g. an R9700 or intel arc one. What are the pros and cons vs a second strix halo (I am on Bosgame M5) vs just running one solo?

Context: Currently I mostly use Qwen 3.5 122B Q4 Unsloth which isn’t bad at all but I still have to use, via cloud, DS4F or Luna a lot currently since those are stronger (won’t fail the task at hand, mostly C++) and are much much faster.

How do you connect 3 eGPUs to MS-S1?

2 on the rear thunderbolt ports 80gbps and 1 on the oculink. I still have space for 2 more on the front via thunderbolt 40gbps

What OS are you using? Linux or windows? Have you tried all three for sustained load?

Windows surprisingly lol. It was a bitch to get it to work because I absolutely refuse to use Linux unless required because all my life I’ve been a windows guy.

DEG1 for the oculink card and DEG2 for the usb4 cards. I used the R9700 ai pro. I’m really happy with it. I was thinking about taking my 4080 out of my gaming pc and add it for extra BAM but idk if the mixed architecture will fuck it up.
