Question Motherboard for two RTX 3090 with NVLINK (4 Slots = 80 mm)

[bm2022]

Hi,
following the previous thread: https://forums.tomshardware.com/threads/motherboard-for-2x-rtx-3090.3692099/

I have two RTX 3090 GPU and a NVLINK (4 slot = 80 mm) distance. I want to buy a new PC. So which motherboard would be best fit in my configuration in 2022? The previous thread said 1600 W or more power supply is also needed. Will i7 processor and 128 GB RAM be adequate?


If there is any expert, would you please give me some suggestions?

Adequate for what? What will this computer be used for?
You'll run into PCIe lane shortages on anything but a HEDT chipset. Best way to get help is to list the parts you are already considering and see what people say.

My job is actually a developer in graphics rendering. Thank you for your insights.
