I have 64 and am about to upgrade to 128GB

I run windows in a VM. Nothing heavy, just to test some things on the shitty windows systems

I run multiple databases, MySQL, PostgreSQL, redis, MongoDB, memcached, all with extra memory available, for development

I run a large array of services directly and in docker containers. Transmission web, the ARR suite, jellyfin, next cloud, immich, onlyofffice, various PHP apps, the list goes on.

8GB is the bare minimum if you only browse 16GB Is the bare minimum if you also run other apps 32GB Is a good amount to work with 64GB is a requirement if you do development or have a lot of services 128GB is a normal amount for a developer
