I am running Vista Ultimate 32 now and would like to migrate to Vista Business 64 (I am also planning on adding a second 8800GTX video card going SLI and bumping up to 8 gigs of OCZ ram (4x2gb, OCZ2T8WC44GK) because it is cheap right now).
Question, is there a way to "upgrade" to Vista 64 from Vista 32 and not have to format my drives and re-install all of my programs? I was going to buy the OEM version of Vista 64, but would buy the retail version if that allowed for an easier upgrade.

Sorry, but Vista 64's Kernel is completely different from Vista 32's. So to go from one to the other requires a clean install.
