I've decided not to upgrade right now until these Poser issues are resolved,  I've only scratched the surface of using Vue 5 Infinite anyhow.  Even with that and a decent system I still had many crashes, I'm going to try to convert my Poser figures to VOB file format in the future (when I get my computer back from having Vista Ultimate Edition uninstalled--a big mistake and waste of money right now until all it's bugs are ironed out).  Thanks to everyone on the forums for helping decide and save much needed cash!
