Althought I'm not an expert on the subject, I have run Vista on a few machines and come away with some criticism.
You should prolly find a machine that's running at least an AMD 2800+ or an Intel Celeron 3xx or Pentium 5xx series with at least 512mb (1gb recommended) and a current video card such as and ATI X200 or higher, Nvidia 6600 or better Recommended for best graphics. Now this being said, you can run it on LESS, but Don't.
Vista is power hungry, and wants to be the very best although that's debateable.
Now I would use a removeable/Hot Swappable drive for the installation of Vista because it may write KEYS to you XP partition depending on what build you have.
PS WOW and WOW64 do not seem stable. Therefore, i would not load too many non microsoft programs at this point b/c they may crash your system. A good reason for Running Vista at this point is o gain a Technical understanding of the OS, Not as a practical choice for an end user.
DISCLAIMER: The Hardware recommended here is NO Reflection of actual minimum or maximum requirements. I stated these items with the understanding that vista will be graphically intense and offer more backround processes to better operate. This is based on MS's Goal for Vista which they state loosley on their web site. NONE OF THIS (In my Reply) to be taken for FACT.
Good Luck using Vista
