Just because an app is running in 4 threads does not mean it will only ever touch 4 cores. Threads can be swapped between cores per step - you WANT this to happen, otherwise it could happen that a borked thread could make a whole core 100% busy until it is killed. A given thread cannot be executed on more than one core per step though. Poser 7 (and I'm pretty certain Poser Pro also) is capped at 4 threads - no matter how many cores you have, more than 4 won't improve render speed in an otherwise idle environment.
Optimal use of your CPU means the usage graphs are pegged at 100%. In the i7 example above, the cores are very obviously not 100% :)
