Just a side thought. Would you like to try answering these questions (respond in the usual way by leaving a comment):
Are you using MCPs (where multicore means four or more processor cores on a chip)? If the answer is "Yes", then can you estimate how much the throughput of whatever activity - or activities - you are involved in (business, particular application or whatever) has improved (let's say expressed as an approximate percentage *) as result of deploying them?
Finally - and this is the big one: Are you in a position to able to estimate the financial benefit to your organisation from the improvement? Most people won't be able to answer that one I expect, but...
* So, if your process has doubled its throughput through the application of MCPs then the improvement is 100%; if it's half as good again as it was, then 50% etc. Don't forget that we are talking about the whole process so it is quite possible for a quad-core system to enable a ten-fold increase in application throughput, for example
