In our final "gaming" related test we look at the performance of one key feature that this card offers, dual BIOS. Having two BIOS versions available on the card allows us to flash one safe in the knowledge that we can simply flick a switch to restore our card to a working state if the flash goes wrong. The aim of the flash is of course to see if we can enable 6970 specifications on our card to enhance performance without any extra cost and in the case of our review sample we had no problems completing this task which enhanced the 3D Mark score by nearly 500 points.
