I'd suggest using a third-party hypervisor, rather than Hyper-V, as there are only a few cards that are supported for direct passthrough with Hyper-V, and they're all expensive. I know that VirtualBox has some support for 3d graphics processing.

You can find a rig that plays XP-era games literally in a dumpster, and XP is laughably easy to crack.
