Ok gents. I currently use WinXP32. I plan to upgrade to a Q6600 and 4 gigs of ram. Will I have to purchase Vista 64bit or can I somehow get XP64 for nothing. I have been told that if I have a licensed copy of XP32 then I should be able to get a 64bit copy for free. Is this true? I really would love to be able to save myself $150 right now.
