I'm just going to reiterate something we all already know. Perform these mods at your own risk!!! I bought a X800pro from Compusa when they first came out. I was quite happy with its performance, good frame rates, great overclocker 520/560+ etc...At stock speeds I was getting 10+ 3dMark2003 scores, 11+ overclocked. I decided to try to flash my card to an XT. It didnt work. The bios flashed to XT but only 12pipes enabled. My card has not worked properly ever since. I reflashed the card back to original bios, however the card will not reach pervious overclocking speeds, none of the new drivers will work with the card anymore. I can only use the card with the outdated drivers, as a result I dont get near the fps I used to. I wish I would have left well enough alone. Performe any mods at your own risk!!! Any modding voids warranty. Though I am going to try and send the cerd back to ATI anyways. I certainly dont have another 400 hundred dollars for a new card.
