Aye @ghostman.

Actually, it's the RAM size that matters, because that's where all data must be stored.

Poser itself might become a problem if it comes to handle all this data during posing or moving cameras, but in case Poser slugs down you can still resort to making elements which are not not needed right now invisible. That helps a LOT when posing in complex scenes!

Also, always remember to check "Multi-threaded Bending" in your "General Preferences" if you have a multi-core processor. This will use all the processor cores for bending / moving, etc, instead of just one, while the others sit idle.
