One Gigabyte 6870OC has a BIOS orginally F3 which I updated to F5, and the other has a BIOS of F20 with no update available.

One card was an RMA replacement for my dead 4870X2, and the other I bought in December as the partner for Cross Fire.

Just wondering why two of the same model would have different Biosessess ?.

If I needed to know which card is which, I would need to go up to the loft and find the box which has all the extra goodies in it, as that is the one I bought and only removed the card.
