What's your current bottleneck? Memory, Disk I/O or CPU? There is more to consider these days than RAW speed. Heat dissipation and power requirements are also a concern.

My colleague and I can't agree which model to choose from. 3 ghz 1333 FSB 120W 2 ghz 1333 FSB 80W 1.86 ghz 1066 FSB 50W I think we should buy the fastest CPU available, just on principle. He thinks we should buy the lowest-power CPU (1.86 Ghz) we can get away with. Our current servers, typically run less than 30% utilization. These new servers will host 40-50 users with desktop sessions and Pub. Apps. What do you all think? thanks Dave This e-mail communication and any attachments may contain confidential and privileged information for the use of the designated recipients named above.
