How do I know if this GPU comes pre-overclocked?

Solution
You can tell if a GPU is overclocked by comparing the clock rates of that card vs the announced specifications. Also most companies will advertise that the card is overclocked. The linked to card is not overclocked. The overclocked ones of that model seem to all have OC in the name.
