It seems like there will be different designs of the upcoming GeForce 9800GX2 cards depending on how much the partner wants to pay Nvidia for the cards, or maybe this has been done to differentiate between the cards, but we know one thing for sure, some cards won't come with the optical S/PIDF that we've seen on the early board pictures.

The reason we say this is that we have an image of one type of S/PDIF solution which can either use an internal S/PDIF header or an external coaxial S/PDIF connector, rather than the front mounted optical S/PDIF input seen earlier.

This should be a neater solution for those that have internal S/PDIF headers on their motherboard or sound card and it would also be the preferred choice if your sound card or motherboard doesn't have an optical S/PDIF input.
