Thanks to Mackey D for the heads up! that people are successfully softmodding their X800 Pro Vivo based cards into XT's, enabling the extra 4 pipelines. apparently the Vivo based cards are identical to the XT in every respect, including the 1.6ns memory and intact bridges, all that is needed is the right BIOS to unlock the remaining 4 pipelines. Some threads going on other forums at the moment about people that have successfully soft modded the current batch of Club3D X800 Pro Vivo cards to XT by flashing with a Gigabyte Bios. These cards are shipping with the 1.6ns Ram, bridges still intact and even have XT stickers on the HSF - by all accounts they are effectively XT cards with 4 pipelines disables in the bios
