Bootcamp: is there an advantage of 64-bit vs 32-bit Windows? I've got the new MabookPro retina. I want to install a dual boot Windows OS.

I have the option from MSDN to either install a 64-bit or a 32-bit. Is there a performance advantage? Other advantages?
According to the store pages, it looks like all the retina models have 8GB memory, with option for more, and as such you should choose the 64-bit version to make sure you can take advantage of all that memory in Windows.

A 32-bit Windows installation would only be able to use 2GB/3GB of the available memory.
