I tried several different Google searches, but I cannot find a dual q6600 motherboard. I suspect something will be developed. There are just too many of us that would buy something like that. If you spot a motherboard for quad-core processors that has more than four memory slots let us know.

As has been abundantly pointed out, there are many more computers with dual or quad cores that run a 32-bit operating system than a 64-bit one. But, there are far less computers with 32 cores upon which Poser is likely to be installed than there are intalled 64-bit computers.

Seeing that the software for 64-bit rendering is already written (which still allows rendering with a 32-bit OS), the real question is why not have both in Poser 8? As far as compiling all of Poser as a 64-bit application, I don't expect that for years.
