My PC has an Intel Xeon from 2007, a GPU from 2010, and 4GB of RAM. It’s enough for web browsing and can handle 1080p/60fps video just fine.

For gaming, I have a dedicated device - a Nintendo Switch, but I also play indie PC games like Slay the Spire, Forge MTG, some puzzle games e.g. TIS-100.

Linux with i3 is fast and responsive. I write code in the terminal, no fancy debuggers, no million plugins, no Electron mess.

It’s enough for everything I need, and I don’t see a reason to ever upgrade. Unless my hardware starts failing, of course.
