lemur01 you should be able to get the 16bit games to work with the compatability settings set to windows 95 for most of them. Poser4 works without having to change compatability settings at all which was a pleasant surprise for me. The more memory you throw at XP the happier it is, I've given it 1Gb to chew on & it runs like a dream. one small piece of advice I have is if you buy a new machine, buy a decent soundcard to go with it, don't use the one built into the motherboard, it really slows the machine down if you listen to music while you render like I do.
