Need a Some Help with setting up an Virtual Machine & GPU Pass-Through

Well, there is a GUI for creating and managing the VM. It is called virt-manager. You will also need QEMU, KVM, and VFIO installed. Windows 8+ and OVMF(separate install) is easier to setup than Windows 7 or lower and Seabios(default in QEMU).

I can not help you very much with how much info you have given. You have to tell us what exactly is not working, or where you are stuck and what steps you have completed)

This guide is what I mostly used, and it should mostly work for you, just google how to do it in mint if the particular command does not work.-
