it's a mistake. They screw up the numbers (mixed 6700K results with 6700 non k).
I'm confused at how the i7-6700K is the winner here! And the numbers are about equal in every bench that the i7-6700k wins. However, the i7-6700 is rated higher and cost less and uses less power!
Im gonna be streaming games as well and im gonna get the gtx 1080
just stay on 6-8 core. wait for cpu s wit 8-16 cores and ?? treads. fallout 4 with 8gb ram 2gb gpu gtx 960 2gb gaming version can hold 4k but slite. msi h110m pro-vh. go for 4-5th gen with 6-8 cores and a good gpu 970-x80 and 8-128 gb ram aboard with a good ssd hybrid. then we can talk.
If the only hardware intensive applications you use are aaa games, save some money and go for an i3/i5 and put more of your budget into your gpu, Idk your situation so if u have questions...
For Gaming will be the 6700 be enough?
