64 bit
I am not that knowledgeable about this, but a Small Dog sales rep told me that Windows has to emulate 32 bit (unless you use the 64 bit version which apparently doesn't have many drivers) so it is very slow. True?
Glen Quagmire said:XP Home supports one processor (with any number of cores).
XP Pro supports two processors (with any number of cores).
If you want to take advantage of both the CPUs in a Mac Pro, you need XP Pro. XP Home would suffice for any other, non-Woodcrest Mac (i.e. anything but the XServe).
