I’m not sure how you feel about upgradability or if you need to have resolutions over 1440p, but aside from those downsides, the Steam Machine is the best deal in PC gaming right now, and would be an upgrade in your case.

It’s likely going to be able to run new AAA games for at least the first half of the PS6 generation while likely being way cheaper now than what Sony will sell its competitor for. It’s also incredible at emulating everything up to Switch, and even Bloodborne on PS4, and I can say from experience that it handles PS3/GameCube/PS2 amazingly well.

And unlike most Mini PC manufacturers, Valve makes high-quality, long-lasting products, and you can find detailed guides and replacement parts on ifixit. I’ve had awful experiences with companies like Minisforum, but I am a Steam Machine user and I can honestly say it’s the best “console” or PC I’ve ever owned.
