What is the best hardware equipment for the HP ProLinat DL380 G6 with vShpere Hypervisor.

I am planning to install an HP ProLinat DL380 G6 with the newest VMware vSphere Hypervisor.
There should be 3 virtual machines: 2x Microsoft Windows Server 2003 and 1x Ubuntu Server 12.04 LTS. 1 Microsoft Windows Server is for the companys network, the othere 2 machines are only webservers.
Please can anyone give me some hints, how I choose the best hardware equipment of our G6? Wich cpu (X, L or E). How many cpu's? How many ram (32GB is the maximum of the free vShpere Hypervisor)... and so on.
