I've got 64gb RAM on my machine but the highest I've seen it was 36gb on arch. (City-sim game running + 20 YouTube tabs.
I was able to stick to 16GB on my Windows 11 gaming VM for ages. Only recently cracked because I was using the OBS replay buffer that was using 2-4GB so I upped to 24GB.
I would never recommend somebody build a new gaming system with less than 32GB now though since you will need an upgrade at some point. If you’re already running 16GB then it’s probably fine to just wait until you do a full re-build.
That said, 16GB is probably the new standard for normal PCs if you’re hoping to get 5 years out of them.
