We need to upgrade our Small Business Server 4.5 to SBS 2003 and are trying to decide upon the best hardware solution. Our current server is a Compaq Proliant 1600, Raid 5, 10k rpm drives Server with about 700 mb of memory.

Primarily we are running Mail Order Manager Software that is written in VFP 8. We also use the server for file and print sharing, and exchange server.

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?

Many thanks.
