Graphics card HD7850 problem

Hello i am thinking of building a new pc in the next few weeks and i stumbled across the HD 7850, i searched it on amazon and found 2 versions of it, both made by sapphire, there was a 4 pounds difference and i found an unboxing video on youtube and the card looks different then in the pictures but what is the difference between the two apart from the price?

HD 7850 1: http://www.amazon.co.uk/Sapphire-11200-14-20G-Card-HD7850-GDDR5/dp/B008HV63F0/ref=sr_1_1?s=computers&ie=UTF8&qid=1351610460&sr=1-1

  1. one is OC the other one is not
  2. But what i find weird is that the OC version is cheaper? is there something wrong? or they might have priced them wrong?
  3. Both the cards are same.
    The first one is an Overclocked card.
    the second one is a factory clock card.

    Now what is overclock and factory clock ? If you dont know then...

    Overclocking is the process of making a computer or component (graphic card) operate faster than the clock frequency specified by the manufacturer by modifying system parameters. One of the most important techniques is running at a higher clock rate (more clock cycles per second; hence the name "overclocking"), but other parameters, such as memory timings, can also be changed and would be considered to be overclocking. Operating voltages may also be changed (increased), which can increase the speed at which operation remains stable. Most overclocking techniques increase power consumption, generating more heat.

    Factory clock is the process of making a computer or component (graphic card) operate according to the clock frequency specified by the manufacturer.Factory clocked components runs on proper power consumption, generates less or desirable heat,thus they are more stable and have better life span.

    So you have to decide,wether you want a faster performing card (OC) giving better framerates or the stable card with better life (factory clock)
    you can also overclock the factroy clock card whenever you want.
  4. So you cant go wrong with either really? and thanks for the detailed answer :)
