LostCircuits posted a review on the Sapphire X800 GTO video card

Once again, Sapphire is releasing a hidden jewel into the market, this time it is the X800 GTO2, a card based on the R480 GPU and boasting 1.6 ns GDDR3 --- and the entire thing sells for about US$ 200.-. From a marketing, logistics and legal standpoint, this is is only possible because officially the card is specked to run on 12 pipelines only at a core and memory speed of 400 and 490 MHz, respectively. In contrast to the X800 Pro series in which some cards could be modded to full 16 pipeline functionality by means of a BIOS flash along with the necessary bridging of blown substrate fuses, the current version only requires a BIOS update to live up to its fullest potential. In the best case, we were able to achieve approximately 70 % overall performance increase over the original configuration of the same, physically identical card. So what did we have to do for this other than selling our souls to the Sapphire aliens?
