According to VR-Zone the launch date for GeForce 9800 GX2 has been set to March 11th this year. The second NVIDIA dual card will see public for the first time during this year's CeBIT. Working samples and final specs are still to be released. NVIDIA has also asked its partners to put a label on their product boxes to address concerns about end users plugging in the 8-pin connector for motherboard into the 8-pin PCIe power connector on the 9800GX2 card.
