Since this is not a high end card it does not require double PCI-E power cables, you only need one to power this beast. You can remove the heatsink and cooler by releasing the four back screws that are placed in the center of the card.

In 2011 we can see that the total score is very similar on these cards and the graphics score it a tad higher on the older 6870. You might wonder why I chose the 6870 to compare against; the reason is that I am lacking a decent card to compare vs and alot of people have the 6850 and 6870 cards so its a fair card to use.  The 6870 at its time was a high end card.
