My humble and limited experience:
1. Always prefer VRAM amount vs. speed.
2. Get blower cards or Founder's for the 3000 series. All the other are more or less poor quality and blow a lot of heat inside your case.
3. If you just need to use two cards, x570 and ryzen 3000 do provide a lot of value (x8/x8, 4.0).
4. Consider that used scalables are quite cheap these days. I got a 8260M QS for 350 eur and it's like new.
5. Some epycs are cheap too (these days the 7282 can be had for less than 600$/eur).
6. I found experimentally that three 2060 Super are on par with a single 3090 in terms of performance. Four of them (~1500$/eur) are superior and do have more VRAM. *And* they are available.
7. If you have a lot of cards in a tight setup, do use pcie cable extenders to separate them.
8. Best cases in my experience for multi-gpu setups.. Tower: Fractal 7 XL and EnthooPro 2. Rack: Chenbro RM41300-F81.
