I know there is a similar thread, and I do not want Vista, but I have a AMD 64 6400+ dual-core with 4 gigs of RAM. I installed XP 32 bit to avoid problems. And, I have no real problems. However, will Poser run faster on a 64 bit OS? I would like to upgrade before you can't buy XP 64 bit anymore if it would be a better OS. Is it? Or is my 32 bit XP good enough? Thanks

PS. MY dual core is much faster than my old 3.4 gHZ Pentium 4 single core that has 2 gigs of RAM, even though the 6400+ is rated at 3.0 GHZ. I see a big difference. So would a 64 bit OS be even better or not?
