Then again, would you be returning it to the manufacturer or the store where you purchased it? I am fairly certain that the Amazon's and NewEgg's of the world do not run bios checkers when video boards (or any boards for that matter) are returned. I have in fact done precisely that. Not because OC broke the board, but because even with OC, the board was not as powerful as I had hoped. So I returned it (reset the OC back to factory beforehand) and ordered the best card I could afford.
