This is the card that your host machine will use when your Gaming VM is up and running. Platforms with iGPUs don’t need an additional card, but Intel HEDT and AMD platforms will. If you need to drive a lot of monitors, do creative work, or want to game on your host in addition to your VM, feel free to get a higher powered card. We’ve chosen the GT 710 as a catch-all Host GPU because it can drive multiple monitors, and only costs around $40 USD.
Note: choosing the same model of card, or in some circumstances, even the same manufacturer as you use on your guest VM can cause problems. A good rule of thumb is to go with AMD on the host if you use Nvidia on your Gaming VM, and vice versa. While not 100% necessary, this will avoid complicated vfio-pci and modprobe configurations.
