I ran install tests on Fedora Core 1 and posted them here:
http://www.redhat.com/archives/fedora-list/2004-February/msg03789.html

Summary: 64MB for graphical, 40 MB minimum.

Personally, I'd install 128MB if possible because it really helps the
performance.  But if you disable little-used services 64MB is fine.

Erm, you could always use vmstat if you want something like vmstat.

$ vmstat
