I7 5820k or 5930k

Solution
Unless you are running 3 or more video cards, then the 5930k does not make any sense price/performance wise. The difference is 200 MHz, which considering that both chips overclock the same way, I see that to be completely irrelevant.

Solution
The only difference I could find on Intel Ark is that the 5930K has 12 more PCI Express lanes and a mild higher clock speed. Should translate to about 5% more performance in real world.
 
The 5820k will be just as good as the 5930k. The only reason I would suggest going for a 5930k is if you want to burn some money, other than that the 5820k is way better in a price/performance perspective.
