Everything I've read about the X1900XT have always had another brand... sapphire, asus, powercolor, e.t.c. Are the BIOS'es specific to the cards make? If so, whould I need a GeCube X1900XTX bios to flash it up? and if so, anyone got a GeCube Radeon X1900XTX bios around? ^_^ And one more question... if/when I flash my XT to XTX, can I/should I/do I (have to) change the clock frequencies to match (manually)? And will the cooling that comes with it be able to handle that change or do I need to poke another fan in there? thx in advance.
