"Free" memory is actually usually used for cache. So instead of waiting to get data from the disk, the system can just read it directly from RAM after the first access. The more RAM you have, the more free space you'll have to use for cache. My machine often has over 20GB of RAM used as cache. You can see this with free -m. IIRC both Gnome and KDE's system managers also show that now.

I actually have my ~/.cache mounted as a tmpfs. No need to write that to disk when I have like 50GB of free RAM most of the time.
