Those are some good specs on that system
I noticed when i was upgrading the pc's, I've got more power = more polys, more detail ... then single frames where taking an up to 90mins to render.
some scenes took a week to render, even when layering.
I built a dual core 4 node render farm, with render server, power bill goes way
up running 6 pc's. I was looking at octo cores earlier in the year and felt way behind on that, not sure who's better.
One thing though, if i went to 64bit system, the 32bit software can't use all that extra ram, is that right?
cheers.
