I did that for years and I recommend it as well. Pure linux desktop + console for games is a nice combo and a good separation of functions.

Of course... at this point I am back to having a PC with a beastly GPU and I boot Windows for games and CAD. It is hard to resist high framerate 4k gaming once it becomes a possibility, so now I need to figure out the secure boot problem for the occasional game that requires it.

A PS5 is an even more locked down system! There are vastly more games, many I already own, that work on Linux.

I'd much rather invest one powerful machine that cand do work and games instead of two that take up extra space and generate more e-waste.
