Best practice for a web farm?

I am running a fairly typical web app (Drupal based) on a LAMP stack
and I am about to buy new servers. What's better, putting heaps of RAM
into each frontend (say, 8GB) and caching locally or have separate
boxes which only run memcached ? I plan quad core CPUs (Xeon 5405 or
so) for the web frontends, but even dual quad cores are not out of
question. If you guys say that go for separate boxes, what kind of CPU
power do I need to plan on?
