I've just bought a new PC with AMD64 and was wondering whether I should use X64 rather than XP. I did a search of the forum and came across threads that advised AGAINST it, but they were dated mid-2005. Has the situation changed? Can anyone who actually uses this OS point-out benefits or pitfalls? Do 32-bit programs run quicker/slower/the same? Can I post more questions when I think of them :suspiciou ! Any help would be GREATLY appreciated!
