I’m building this as a Plex/gaming vm so I’d put an RTX 4070 into the PCI 5.0x16 CPU slot.
Then for the other slots I’d really only need one 10GB Ethernet card and one USB 3 extension card (to pass through to my VM) and maybe in the future another SATA extension card for spinning hard drives. So no SSD storage would go into any of the PCI slots.
my biggest worry is the IOMMU configuration, though. As I can’t find anything on this and I need to pass a couple of things into my VM. (Graphics card, usb3 extension card, and one of the M2 drives)
