Very possible but there's nothing to do aside from changing to a different socket/chipset. You could likely pick up something acceptable (way better) on CL/Facebook market for cheap if you're patient enough.
It's around the same as the other cards I mentioned. The Radeon cards are around 100 and the NV are 70 - 100ish depending on which. The 720 should be under 30W, much worse performance but should be fine for what Grouch is limited to playing.
