I'm on a similar train. My old PC can still run around half of new games but I can see the struggle. I'm considering going for a mid to low range laptop with Linux for everyday stuff and move my gaming to a Steam Deck. I ran the numbers and this option is around $750 cheaper than building a new mid level PC the way I want it. Unless I get a big downfall, the Deck+Laptop way is gonna have to do in the next year or so.
