CES 2011, Las Vegas - NVIDIA partner EVGA has shown off some dual-Fermi GPU based goodness. The dual-GPU will be based off of two GTX500 series GPU's, which exact GPU's is unknown at the moment.
The card has 3 DVI outputs, which would lead us to believe it's Surround Vision-capable from the single PCIe product. The card requires dual 8-pin PCIe power, so you'll need some a decent PSU to run this beast. The card also includes SLI which should be capable of attaching another dual-GPU based card and going for 4-way action.
The triple fan looks the goods too, so it should keep the card both cool and quiet.
