I don't know, I have never updated a processor so have no idea how it would show up in System Profiler. I would assume the speed and type of processor should show up under hardware but then again I don't know if this is info that has been saved to a file or if the machine checks every time you open System Profiler. With memory upgrades it shows immediately so you would think that a processor should as well.
