D8E, Nvidia's dual G92 card will be ready for late January. The card with two PCBs and two power connectors will be an internal SLI concept and, naturally, you will be able to put two of these together.
This is sort of a passage card, which will get Nvidia by for a few months before it is ready to announce its G100 D9E chip.
The only problem with this card is that you will need a good SLI driver to get a decent performance from two chipsets; but from this stage even the future of graphics looks multi-core.
We are still not sure if Nvidia plans to introduce the card in January or whether it will wait a bit longer; but it is obvious that it will be too late for for the holiday 2007 shopping spree.
