I am trying to figure out how, where, and how much it would cost to upgrade my 8 core 2.4 Ghz prossessors to the 12 core 3.06's?
Very few 8-processor Mac Pro machines are compute-bound. Most are severely I/O bound.
What sort of work are you doing on this Mac that requires more compute-power ??
What is your Memory and Hard drive configuration?
Maybe start with Intel processor list of just what they have maybe in 8-core 3.2GHZ first and the MSRP vs eBay and Amazon etc
There is a lot in one or two only long threads on MacRumors forum under Mac Pro desktop section about processor upgrades.
You could be looking at 2x$1500 easily.
