Probably not the answer you were expecting, but you may want to consider getting an Xbox Series S (that is often on sale at $250 or even $200), plugin your mouse and keyboard and you'll have a great experience. Yes that is a "dedicated game rig" but much more affordable than a usable gaming PC. Of course, only if you also play other games on that xbox and can live with no disc. This is what I would do in your situation.
