High Performance Power Plan and Ultimate Performance Power Plan.

As Greg's second linked article points out, the Ultimate plan is only beneficial in uncommon circumstances, such as professional level

3D modelling and workstations, which is why it's not available on Win10 Home.

"People who use their hardware in such a way that it needs to constantly go from an idle state to a fully-loaded state will

enjoy the most benefit from this feature. Most ordinary people, including gamers and people who render video for a living,

won’t necessarily see a large boost."

There is no benefit to gamers because, once the cpu/gpu ramp up to 3D mode clock speeds and the game has loaded,

games run with a fairly constant power use.

I believe the term Ultimate is really more in reference to forcing constant full power on all components, not increasing

artificial benchmark tests, which if you ran a number of times would likely show a different result each time.

It's more about reducing micro-latency in specific real world situations, due to cycling of component power states.

If the machine is not being used in a professional capacity forcing full power on all components 100% of the time is just a

waste of power, and creator of unnecessary heat.

btw - GTX1060/1060 ti  is mid range in the GTX lineup (GT series not being part of their 'gaming' gpu's). 

1070 Mid/high, and high - 1080/1080ti, or SLI 1070/1080.

The i7 8700 is indeed high end, and if you are doing cpu intensive tasks in a professional capacity the cpu is more important than the

gpu, but if you are looking for gaming performance the money would have been better spent using an i5 8600 with an GTX1080.

Partly because Hyper-threading does not greatly benefit a lot of games, and will cause some games run poorly or even crash

(maybe not so much with very recent games), and partly because games are more gpu intensive than cpu intensive.
