Ya I saw that. I guess its good maybe if you have an older or cheaper card, but I would be afraid of ruining the card by flashing it's Bios. It's probably not as big of a deal as flashing your motherboard's Bios but still.

I was a little leary about that too, since the cost of some high end cards is a few hundred dollars. You can always revert back to stock bios settings by re flashing the bios. One major drawback is if you mess up the flash you have a very expensive paper weight. Not for the feint of heart (myself included). Tis the price of over clocking.
