A few independent sources have confirmed that the D9E, NVIDIA's sandwich board will officially launch as GeForce 9800 GX2. The add in boards partners got the final okay on the name so they can now proceed on designing their own boxes and printing. And there is no way back from there. A few sources also independently confirmed that the board should launch by mid February time. The GeForce 9800 GX2 will have a massive cooler in-between two PCB's. The cooler itself will have a two copper parts that will fit on the GPU's and it will be placed in the middle. At the end, when looking at the gaming performance matters this GX2 will be fastest graphics card around. At least for a while. - FudZilla

NVIDIA GeForce 9800 GX2, Official Dual-GPU Naming

The board needs two power connectors one 6-pin and one 8-pin and it will need about 200W. It will run very hot but we are sure it will be stable. We said this back in 2007 but let us be clear on one thing. NVIDIA's upcoming high-end sandwich board, the GeForce 9800 GX2 is going to end up faster than a single Radeon 3870 X2 card. This comes as no surprise as NVIDIA's single G92 is faster than a single RV670 and in the same matter a dual chip NVIDIA version beats ATI edition. The Radeon 3870 X2 will be very competitive as its single chip brother was but it is still a bit slower compared to NVIDIA.

We still believe that the Radeon 3870 X2 card will have quite good sales as it will be significantly cooler than NVIDIA's card and it will be available in massive numbers. The cards will feature a single SLI connector, which means that you can forget about running more than a pair of these cards at once. Let's just hope that NVIDIA puts a bit more effort into supporting these cards with drivers than they did with the GeForce 7950 GX2 video cards. But at least with the 3-Way SLI technology already working much better then the Quad SLI feature should benifit from this driver development as well.
