Is this true about my Windows 7 Pro License?

I bought a Windows 7 Professional License, it was an OEM and it says system builder edition on the small box

Is it true that after I sell my laptop, that license dies and I cannot use it on another laptop if I format the current laptop? ie. it is not transferable?

a post from a user on Anandtech forums:

Microsoft's standing definition is that the computer is the motherboard. It is the heart of the computer and the part you're least likely to replace on its own. As such OEM licenses are tied to the motherboard, with this lifted in the case where a motherboard replacement is necessary for a computer repair.

Please tell meh he is wrong
