WOW!!! I Didn't even think such machines existed...Is all this people working for NASA, CIA or what?! By the way, it's exactly what I needed to know: now I understand I was really asking too much to my "poor" P4 256RAM - again, it's ridiculous that CL "reccomends" 256RAM for Poser5 - and that I'll have to make an upgrade that will be not exactly cheap... Thanks Mike and to all the other ones who posted a reply. Alberto
