Sapphire is a well-known ATi partner. Their graphic cards and motherboards are popular world-wide. It seems that Sapphire has shipped many X1800GTO2 units to world-wide shops already. Sapphire introduced the GTO2 line with their X800 boards. The GTO2 name is quite popular due to its price, overclocking, and its high potential unlocking extra pipelines. Many X800GTO2 cards were actually X850XT PE's with better memory in disguise. All you have to do to convert your X800GTO2 into a very powerful X850XT PE, is to simply use a BIOS mod. At this point, we don’t know much about the possible hidden performance of this card; but everything will be clear in the near future. According to our sources, the price is going to be around to 200-300$.
Update:

Update #2:
