They really aren't that high. In fact the difference between minimum and recommended is actually quite small. Makes me wonder if that's the minimum for 60FPS. Lately system reqs have been seriously inflated. They're pretty similar to Shadow of Mordor's, and that game ran on systems much less powerful than it's minimum requirements.
Most people should have a Quad Core CPU and 8GB Ram by now. I have a feeling that the game will still perform well on cards less powerful than a 660 or an 7870.
