I have a Sapphire X850 XT PCI-E (not VIVO, but does have TV out) that I got in a trade with a buddy of mine. It runs rock solid stable clocked at PE speeds with any game/benchmark I throw at it. I'd like to flash it, so I don't have to worry about setting the memory/cpu speed in the future. I got ahold of an ATI X850 XT PE PCI-E BIOS, but I just thought I'd get some opinions on doing this, apart from the basic risk of trashing my card. Has anyone here done this kind of flash? I've flashed my 6800 cards up and down the block like a mad pervert in the park, but I haven't done any ATIs yet.
