Hi

What version of vista would I need to purchase in order to make full use of a mac pro's cores when running under bootcamp?

Cheers
 
Get Vista Ultimate. It is the only version that can support the 32GB of RAM that a MacPro can handle if you ever decide to go crazy with the RAM. Make sure to get the 64-bit version though.
 
Windows vista can do no more than 2gb of ram but if you get the vista 64-bit version it can do 3.5gb and any vista will pick up all the cores for your mac pro.

vista-64bit with pae can do 64gb ram but then you dont need to, kinda useless really with how windows utilizes its ram.. just install the vista ultimate 64bit.

I dont think thats accurate - Vista home basic and home premium can only handle a single socket so on an 8core Mac, that means it will only see 4 cores. Business and Ultimate will see dual sockets.

Also I dont think the X64 versions are limited to 3.5GB. Should be able to handle as much as 128GB RAM (in theory). Well I know its more than 3.5GB because I've got 8GB in my Vista64 PC system. That much I'm 100% sure of :)

Any recent 32-bit operating system (XP, Vista) can see up to 3.5gb of ram. You need to run a 64-bit version to use the max of 128gb. Any 64-bit one can see 128gb but you of course have to have the hardware that supports that much to also be supported by the OS.
