Hello,
I'm looking for a motherboard which supports 6+ (dual slot) GPUs for i9-9900K/Ryzen 9/Threadripper 2/XEON. I wont use those GPUs for cryptomining. I'll be running virtual machines with GPU passthrough to 3 macOS VMs and 3 Windows VMs (plus 1-2 Linux VMs if I can find a motherboard which supports so many GPUs.
All those GPUs as well as CPU will be liquid cooled with 1 liquid cooling circuit for 4 GPUs and 1 liquid cooling circuit for 2-3 GPUs & CPU. System will be rack mounted in a 5U for better cooling.
I know that those are expensive as hell.
