or a bios flash. also if you are refering to the XT mod then i can send you a file with all the mod info that you will need .....that is if you have a R360 core. the only way to find that out thoug is to check ubder the hood(the chip is marked either R350 or R360. Also it would be nice if you have a 256MB Pro then you are sure to mod to 9800XT. the performance benefit is minimal but is there. i noticed things being a little smother with my R360 core Pro.
