ASUS has been developing a dual GPU graphic card based on nVidia’s GeForce 6800 and 7800 series. The last is ASUS EN7800GT Dual and uses two 7800GT-circuits on the same PCB. This means in theory that you would be able to run four graphic circuits on a regular SLI-mainboard. Unfortunately nVidia doesn’t have any drivers that supports more than two GPUs in SLI, which also Gigabyte has suffered from with its Quad SLI-mainboard. Now it seems that nVidia has made drivers supporting four GPUs and at the Chinese site PCPOP they’ve published pictures of a system with dual ASUS EN7800GT Dual in a working Quad SLI-configuration.
The graphic cards are installed on a ASUS A8N32-SLI Deluxe Revision 2 motherboard and the picture are suppose to come from ASUS own R&D lab in Taiwan. It also has screenshots of 3Dmark05 where you can see how the rendering is divided among the four GPUs. Very exciting but for some unknown reason we don’t get to see the result from 3Dmark05. This hardly the last we hear from Quad SLI. A big plus for nVidia, but at the same time the costs for Quad SLI-system is almost ridiculous.
