I am buying a new server for an elementary school. We have around 50 iMacs and 600 users. With the recent price drops the dual 1.25 is much cheaper than the single xServe, as well as having much cheaper parts such as extra hard drives. With the dual processors would it have better performance than the single xServe? It would be used ofr some application serving, maybe netbooting and of course file serving. we would be running the newest Jaguar server software.
