When I was looking into processor upgrades for Mac Pro I came across an add for a company that will do the CPU upgrade (now I can't find the page). Anyone have any recommendations?
There are a number of companies on ebay selling the service, price includes CPUS and shipping for your CPU tray. I'm debating doing it myself with two 3.46 hex core.

You can get a pair of X5670s for under ~$900 with some patience and X5680s for $1,500. So I'd really consider whether a. the clock speed is worth that extra (is it going to give you that in productivity?) and b. if it is worth paying someone to do this for you when it is so easy to do.
