The bottom line is if you have a PCI-X slot (its larger than a PCI slot) then you can take advantage of the 64, but you don't have to because a 32 will fit in a 64 slot (theoretically a 64 can be used in a 32 slot but only at the 32 rate and it would be a waste.
I found this info by googling "PCI-X slot"
