I think you'll find those saying they are running anything more than 4-8 "servers" on something like a Dual 3GHz are talking about idle servers.
Here's a nice experiment, go start a L4D lobby (one only) and let it fill. Wait for an infected wave and some specials. Look at your CPU usage. I would tentatively only go as high as 5-6 servers on a Xeon for this reason. L4D servers are highly susceptible to loss of frame rate too.
