SODIMM ram is still cheap. You could build them a ddr4 intel system with integrated graphics (ideally Arc cores or plenty of EUs) that will run some older or simpler games at 40-60fps with a little upscaling, and the whole thing could be done for 500-700 I reckon.

Either that or maybe build an AM4 if you find a used GPU at a good price.

Does this essentially bypass the AMD PSP bit or am I misunderstanding something?

Drilling machines are not made by forcibly kidnapping diggers and making them motion-capture their movements for a robot that pollutes and consumes water by ignoring previous green regulations.
