rdg1101 is probably right. Specs are overdone for that reason. I've also started suspecting that the recommended specs are for 4K and not 1080 gaming. I wish they would let us know what res the specs were for.
But I question how you know a game WILL work with such lower specs. Just because one game works with lower then minimum specs doesn't mean they all will. You can also look at specs as a guideline for what you'll need. If they say you'll need a 3770 or 8350 to run, then you know you'll need an 8thread CPU to run it. A 3570 or 6300 might run it, but expect places where more CPU power is needed and you'll have slow downs.
