I'm about to install Windows Vista Ultimate (boot camp), but I don't know if I should choose the 32 or 64 bit version. I'm talking about my unibody MBP 2,8ghz 4GB RAM. I know only the 64bit can use all 4gigs of RAM installed, but maybe there are some other things I should know about too? A while ago, a list was posted here with all software compatible with Vista x64 (but I can't find it again unfortunately) Can anyone post a link to that list too? Thanks in advance!!!
