I'm using a P4 3.4GHz with 2GB ram with a Nvidia 6600 graphic card.  Not a bad system, but nothing special.  I have no problems with Vue and have had up to four Poser figures in one render (Vicky, dragons, cats, lots of DM building linds of stuff).  My system does me fine.  

I'd like to add one more GB of ram, but haven't really popped the hood on my computer to see what that would intail.  I will think about Vista, but not on this computer - maybe my bare bones system that I built for my daughter.  It's a dual-core system, but rather ham strung with only 1 GB and a cheep video card.  Good enough for a 9 year old, not enough for mom!
