DISCLAIMER: flashing the 1000W bios to your card will void the warranty.
I don't think this is true. However, if you need to submit a warranty claim/RMA, you definitely need to restore the stock vbios to all positions before sending it back. If you send it in with the 1000w flashed, or with the cooler removed, or modified in any way, they will generally refuse to approve the RMA/claim. YMMV as always, EVGA has made exceptions for folks in the past and through various channels. But this is my understanding. If you install a water block, for example, you need to reinstall the stock cooler that shipped w the card to RMA it.
So if you plan to flash a diff bios to any card, always save the stock bios off first.
