i've no idea!
however i serve 2 million pages a month with CONSIDERABLY less spec than that.
i run quite a few sites on the server but i've got highly optimised DB queries (and databases) and a hand crafted CMS, which is VERY specifically built for the exact purpose.
... i think if you use off the shelf software - CMS, Forums etc, they can be very resource hungry!
