I know the Precisions are considered desktops not real servers but...
We have 15-20 T5500 towers that we are considering switching over to the R5500 chassis. Alternately we would sell the T5500's and purchase/upgrade to the R7610 with 8-core CPUs vs. the T5500's which currently have 6-core CPUs.
Question for anyone who has had either of these machines in a rack with metered power situation: When the machines are at idle, does the R7610 draw significantly less power than the R5500?
