>We need to upgrade our Small Business Server 4.5 to SBS 2003 and are trying to decide upon the best hardware solution....Would two Xenon processors make a significant speed difference in this scenario? How much memory should we get for a 10 user system? Will there be a significant speed difference even with just one 3.0 ghz processor?

What are the bottlenecks in your current setup ? Give that feature special attention.
