The i3 6300 is the same as the 6100 minus 100mhz and 1mb of cache, performance should be nearly the same. This is a i3 with a more powerful gpu than the 480, running a cpu intensive game. The point was to highlight the bottleneck as much as possible this would likely be even less apparent if they were using a 480 in the benchmark. The i3 will run the game at ultra settings over 60fps all of the time, if the OP is expecting more than that I agree buy a better cpu. But if you're aiming for 1080p 60fps an i3 6100 and a 480 is a great combination, minus a couple select games the i3 would be just as good as an i5 at achieving ultra settings 1080p 60fps.
