Could you provide a photo of block?
From photos I can see that:
3080 gaming oc differs from 3080 eagle oc with one plug.
Gaming OC uses central solder points, eagle oc uses left (for plug) dunno it is light or fans.
Gaming OC have additional bios, and switch, and eagle does not.
3090 eagle oc uses all three plugs, and have nvlink, and two memory chips on front and some power controllers more. (back is somewhat different because of more memory chips.
capacitors, coils etc are in the same locations.
