Although overclocking tests are exciting, they are only of limited relevance to the real world. The problem is that, even within a family of cards, the spread is too big to allow us to draw any real conclusions. Extensive cooling through huge heatsinks and large (loud) fans may look impressive, but seldom has a tangible effect on overclocking endeavors. These overclocking results should therefore be seen more as a trend of what should be possible. There is no guarantee that any card, even from the same company and of the same family, will reach these speeds as well.
