This thread has now taken a hilarious turn. There is a REASON BIOS flashing isn't covered by the warranty and we are seeing exactly why.

Show me where large batches of non flashed, non-overclocked cards are dying (taking into account that people who experience a problem are more likely to whine than those who don't) and maybe we will have something.

Until then it is just a matter of people wading into BIOS flashing without thinking of the ramifications.
