I want it for that same reason, but with another bit which isn't known yet (I think). If the discrete card supports gvt-g then it'll be the cheapest and easiest way to share full hardware acceleration of a gpu in a vm with a single card. This then also still lets the host use the gpu at the same time. All the offerings from amd and nvidia cost a lot and nvidias even require special licensing.

I will take any discrete GPU that works stably on Linux and is 75W peak draw or under. I hear good things about the newer AMD lineup with the open-source AMD drivers, but even the most low-end of those all take an external power-connector, which puts them over 75W of peak draw.
