Yea, I wish Poser was like bryce 5 with network rendering. I'm sure (if you do a lot) any speed improvements would help. XP Pro supports dual processors, but it's no good if your software isn't written for dual processors. What a waste. Intel hypertheading is trying to do the same thing but it's so minor, you won't notice it. I think Windows server (cluster computing) does the same thing, I'm not sure nor am I willing to shell out $4,000 to find out. But you'll also need special hardware, scisi drives, etc ... and I'm not upgrading. Linux has a program called... m********* (don't remember rest of name) that allows you to combine PC power. I understand Poser can run under some linux OS ... but never tried it.
