Most likely, you will see a slightly slower performance of Poser on dual/quad cores as their processing speeds (mips) are less than single-core cpus.  Increased bus speeds on these newer systems may equalize this.  Poser can't use any more memory than can be alotted a 32-bit process, so a 64-bit system with 128GB memory gains you nothing - for Poser anyway.  Of course, with multiprocessors, you can do more things simultaneously (like render in Poser and check your email)  without the process-swapping hits.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
