In our SLI gaming performance scaling articles we’re going to investigate SLI scaling factors. Today we’re combining an Intel Core i7-5820K processor with two GTX 980 graphics cards from ASUS. Apparently we want to find out how big the performance benefit is when we add a second GTX 980 to our test system. Apart from that we’re investigating the results at 1080p, 1440p as well as 2160p (UHD).
