I’m still running 16GB. I built my PC in 2015 and it’s been my gaming/work/dev machine ever since. Have only upgraded GPU and storage.
It is definitely showing its age, but I don’t need to worry about the Windows requirements. My CPU isn’t supported for Windows 11 so I’m sticking with what I’ve got until Windows 10 hits EoL. Then I’ll probably buy a 64GB AMD system and switch to Mint at that point.
