let's say that i need to save some money and i can't buy new clients, i think a good answer for this could be virtualization.
 - if i understand well my client can boot with a free os and log on on a virtual machine that run win xp, using the performance of the server and not the performance of the client.
that's a good thing (if works like this) the problem is that is very difficult to plan how many virtual machine can hold one single server.

now let's say that i have 3 identical physical server, can i configure them (using windows server 2008 rc2) to act as only one to improve performance?
my goal is to have just one powerful windows server to host different virtual virtual server on top of it (look the picture).
 
ok, i made some assumption but i really don't know where i'm wrong or where i'm right, can you talk about it?

No ... you can't do what you want to do in your picture.
What you can do is pool the resources together in a slightly different way.
In VMWare Terms, this is called a Cluster. Activating features like DRS (Dynamic Resource Scheduling) and HA (High Availalbility) and even DPM (Distributed Power Management) on this cluster means that the total power/memory becomes the net effect of all your servers.
So if you had 3 servers each with 10GB RAM and 10GHz Processing power, your cluster would have 30GB RAM and 30GHz Processing power. DRS,HA,DPM then take over and move over VM's across the servers depending on resource rules, etc. But a VM will run on 1 of those physical machines at any given time.
Here is a more in-depth overview: http://www.petri.co.il/vmware-esx-server-cluster-pools.htm
Hope this helps..
