All in all, that system looks good. The key question in general is just
how large a traffic stream will you be monitoring. The above should be
fine for a good-sized site (say 1000 hosts, in my experience). Much larger
and you'll want to increase the RAM.

That's what we use, generally to good effect. Others may work fine,
too, I don't know.
