Im seriously debating whether to use Microsoft Windows XP Professional or Microsoft Windows XP Professional x64. I have both at my disposal, but which should be used? I like how I can have terrabytes of ram, makes me feel good! But about driver support, does that mean some of my games will be broken? (UNPLAYABLE) Theres another OS out there, called Solaris, is it any good? Does it run .exes? Its free, so thats cool. Dont give me any of this crap "Get a mac, its for real men." I dislike mac, so dont suggest it. If theres a list of games that work perfectly in Windows XP Professional x64, please tell. And its kinda stupid of Microsoft to not allow 16 bit applications to work in Windows XP Professional x64, or not allow any 32 bit drivers to work. There should be a patch for that!!!!
