Usually fairly soon after, CPUs have pretty short shelf-lives these

see my 'oops' follow-up - I forgot to consider the first rev of the Core
architecture, which was 32-bit only and current until Jan 2007. The
follow-up 'Core 2' architecture was x86-64 capable. You probably have a
Core Duo or Core Solo CPU in that thing.

(Core 2 CPUs replaced Core CPUs in shipping models very quickly after
Core 2 was released, which kinda supports my first point of this mail).
