Guru3d has posted an article on taking four GeForce GTX 480 graphics cards and putting them into a 4-way SLI setup. Nvidia has recently released a new driver that enables 4-way SLI. However, there is just one small problem. The only “game” that supports 4-way SLI is 3DMark Vantage, which is not really a game. To prevent the CPU from being the bottleneck, they needed to overclock the Core i7 980 Extreme processor. But then they ran into a new problem. What motherboard would support 4-way SLI? They finally realized that they would need two Nvidia NF200 integrated circuits embedded on the motherboard in order to be able to accomplish this feat. How did they do it and what was their final score? Click the link below to find out.
