One of the most talked about items during CES 2006 was NVIDIA's unveiling of their new QUAD SLI graphics display system - featuring 4 separate graphic card processors (GPU's). I examined the new Dell superbox during my appointment with NVIDIA. It has a reference motherboard from Nvidia. The video cards have two PCB's and two coolers each. In totality, with the 4 GeForce 7800 GTX 512 MB chips (four G70 chips) you have a whopping 2 GB of total graphic memory. You will be able to run to drive a display at 2560 x 1600 with no problems at the highest settings. The way this setup works, is that the video cards are interconnected inside, with only the master card plugged into the PCI Express slot. This way the mobo only needs 2 PCIe slots onboard. If you look closely at the pictures I've attached below you'll see that boards are configured in a father and daughter board fashion. Only the father board plugs into the actual PCIe slot on the motherboard. The SLI bridges connect the fatherboard bridges together, and the 2 daughter boards are connected in a similar way. Please follow this thread into the forums to view the pictures and discuss... thanks!
