>>PS. if there are brand new machines, I'd put 64 bit windows on, then run 32 bit applications. That way your PC can utilise more memory.

>Unfortunately not. A 32-bit application can't use more than 4GB, regardless of how much RAM the 64-bit machine has.

The way I understood it, is each 32 bit process running on 64 bit windows can access a max of 2 gig each. So if you are running 3 memory intensive 32 bit applications they each be able to access a max of 2 gig, utilising a total of 6 gig?
