I have 16GBs of memory here and have /var/tmp/portage/ on tmpfs, no
ccache.  With the growing size of packages, I've had to put several on
regular spinning rust to make sure enough space is available.  This is
my list, so far.

www-client/firefox
www-client/seamonkey
app-office/libreoffice
sys-devel/gcc
dev-qt/qtwebengine
dev-qt/qtwebkit 

Those are the ones that tend to run into space problems.  Keep in mind,
I have twice the memory you have.  As someone else pointed out, if you
start using swap, that generally defeats the purpose of tmpfs. 

While I'm sure plenty of packages will make good use of portage being on
tmpfs, there will be quite a few that will have space problems.  You
will need to be ready to make exceptions for those as they show up but
those in my list are certainly ones that you may want to add before
trying.  There could be exceptions to this based on your habits and
memory requirements for other things but that is my experience so far. 

Hope that helps.
