Do you have your Render processes set us use multiple threads? (general preferences: render tab) That is supposed to spread the load out to the other processors.
Poser 7 only divides the work of rendering once, at the start of the render; so if your scene has a bunch of complicated stuff in the top right corner (e.g.) then it will behave like this. Three cores will drop to idle and 3/4 of your uber quad core processor will sit there and do nothing, while the remainder gimps along on one core until it finishes (which might be hours). I talked to EF about this shortly after Poser 7 was released and they acknowledged it, and told me no change is planned there until "the next version of Poser", but I expect that will not include the upcoming "Pro" version - certainly it isn't enough to get me to buy it, even if it does make it in.
edit: and comparing to other renderers out there, none of the "big dogs" has such a stupid implementation of multiprocessing; if you are rendering in 4 threads/4 cores, and one finishes earlier, the work is re-divided immediately to keep all 4 cores busy, as much as is practical.
