[AG-TECH] upgrade questions

[Darin Oman]

Hi,

We're thinking about upgrading our AG computers soon and any 
documentation I can find discussing requirements is a bit outdated, so 
I'm posting here for some suggestions. Some things I'm wondering:

Is it still necessary to go dual processor, or will a single processor, 
say 2 GHz machine suffice?
Is 4 machines still the recommended way to go?
I'm not very experienced with Linux, so I'm not familiar with 
compatibility issues. If, for example, we bought our machines from Dell 
or Compaq, how difficult would my life be? Is it better to build from 
scratch?
I know some people are using Win XP on their display and/or control 
machines. Is it working OK?

Thanks in advance,

Darin Oman
