32 bit os only address up to 3.25, and there was whole myth thing about how that missing 700MB+ ram missing is use for system I/O, pci, video card. but think it just BS since this explain a little different

http://www.interact-sw.co.uk/iangblo...05/is3gbenough I think you will have more compatibility issue with XP x64 then Vista 64, everyone seem to go forward and support Vista rather then XP

I would consider the latter only in dual boot mode in case of compatibility issues (which I don't have, knock on wood!).

Agree, but I think Vista 64 bit is the way to go if you must use 64 bit, there will be more support in the future where XP will start fade out sometime the end of next year

Agree, I try 64 bit XP, but there were not as much support as Vista 64-bit, so I end up using Vista 64 bit
