I have a desktop with a relatively powerful 5070 (I think) GPU for playing VR games. But my priorities for couch & controller games is not really around super high graphics performance.

Lately I find myself playing classic games on emulator, or generally games without huge graphics demands (been playing that climbing game PEAK a lot lately).

For me, getting a random no-name-brand Mini PC is such a fantastic deal these days. Throw bazzite or now real Steam OS on it, have access to your whole library - it's a linux machine you can configure to your hearts content. I love it. Probably the best deal on amazon right now is this machine, though there's others if you know how to search.

Example of real-life gaming performance here - nothing mindblowing, but more than you'd expect from a tiny box that costs like $400.

Just wipe windows immediately and put SteamOS on it and you're good to go
