Untrue. SP1 fixes this with respect to 32bit Vista. With 64 bit the entire OS is 64 bit so performance benefit is immediate potentially used apps aside, driver issues are fewer than they were... nothing a little research can't resolve.

Your Vista key can be used to activate 32 bit or 64 bit installations of vista but to upgrade to Ultimate you must have the respective 32/64 bit Home Premium/Home Basic (Whatever you are upgrading from) Installed and activated first.
