The guys from VR-Zone have posted a photo of Asus's upcoming GeForce 7800GT-DUAL card. This card will feature two NVIDIA GeForce 7800 GT cores and will be pretty huge.
It has a single 6-pin Molex connector to power two GPUs and it requires an external power source using an AC adapter. The card has two DVI-outs and two VGA connectors.
I wonder how this card will perform compared to a SLI system and whether it will be cheaper than two 7800GTs in SLI.
