In our 3-way SLI gaming performance scaling articles we're going to investigate 3-way SLI scaling factors with different CPUs and different clock speeds. In eight recent games and two theoretical benchmarks we want to find out what difference 3-way SLI makes, when we run benchmarks with the CPU at stock clocks as well as overclocked to 4.5 GHz. Let's kick off with an Intel 3960X CPU and three ASUS GTX 780 DirectCU II graphics cards and find out what the differences are going to be like.
