'But can the 32 bit app see/utilize more than 2G Ram?'

I went looking for the answer and basically according to the Microsoft site, it's totally down to the program, if they are large memory enabled they can address up to 3Gb on 32 or 64 bit OS, after effects and photoshop have always been enabled if turned on, I assume Vue will be the same, also XP 64 will enable the 32 bit program to use all 3Gb as it can address 1Tb of memory (1000Mb) unlike the 32 bit which used to eat into that 3Gb before any program was ran.
Hope this helps.
