From what I have read, 32 bit can only support 4 gigs of memory which includes video memory so even if you dont crossfire and have a 512mb video card then you can only have 3.5 gigs of RAM, add any more and your PC simply will not see it. I am just telling you what I know and I have no incentive to lie, if I am providing false information please correct me for I would like to know more as well.
But as I have said, I have Vista 64bit and all of the compatibility issues can be easily resolved, I am currently playing Grim Fandango and that's a 10 year old game. Took me about 5 - 10 minutes of googling to figure out how to properly run it but it is a minor one time inconvenience.
