NGOHQ has spotted Sapphire’s X1800GTO2 on the market.  While they have yet to test it out, it is likely that at least some can be transformed into a X850XT PE with a BIOS tweak.
“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.”
