Add two more things to the mix: Poser doesn't use OpenGL, so memory on board becomes even more important compared to video memory; and Daz Studio will, although I don't remember is it supports dual processors. It sounds like you're spreading out. To be honest, not many software packages take advantage of dual processors. However, if you've got money to burn, more is ALWAYS better. The speed of the processor right now is way ahead of most software. There won't be much difference between any high end processor in the way of speed. Memory plays a much more important role now. The more memory, the better. Youwant to remember to get either Windows XP or Win 2000 pro. Other Windows systems have an upward limit on memory use. If I remember right, Win 98 would only address 64 meg of memory on the main release, and the update only let you go to 128 meg. I got a tremendous performance boost when I switched to XP.
