This is what pretty much made your whole post completely loose all legitimacy to be honest. The logic you are trying to convey is that it has to be good because they put so much time and effort into it. That logic is laughable and bewildering at best. Let me educate you with a fantastic word in the English language. Very relevant here. subjective influenced by or based on personal beliefs or feelings, rather than based on facts:

While the IPC of the Intel chip is higher, the Radeon graphics in said A8 and A10 is vastly better, which will give better performance in games overall. Even with the weaker CPU.

You would need to upgrade your PSU to about 300w minimum. Worth doing though, will add a nice bit of graphical power to that system.

The 1060 has pretty much twice the power of a 1050ti, plus, the 6GB model of the 1060 has a nice bit of vram going forward.

For the most part, a 1050ti draws most of its power through the PCIE bus. While it is not recommended to use an adapter to give you a molex connector, it should be fine in the this case, seeing as the 1050ti will draw small amounts of power from the molex at best. It is always best to have a PSU that has molex connectors though.

The max temp a 1060 can handle is 94 degrees. So you are within the limits just fine, even though you are near the upper limit. It is still within the limit. The card is always going to run hotter in a laptop though as its crammed into a smaller space. The card would automatically lower its speed to keep within the temp limits if it was getting to hot. Get something like MSI afterburner and use it to monitor the clock speeds and fan speee when gaming. If your clock speeds are full and the fan is not maxing out then you still have alot of headroom with heat, as the fan can spin hotter and it is not thermal throttling. If you see the fan hitting max usage and or the clock speed lowering then you probably have lots of dust in the vents.

My Gigabite 1060 6GB will idle at around 40 celcius when i start the PC up from cold. After I have played a game, it will idle at around 58 degress, still low enough to not have the fans spinning. This is with clock and memory speeds at low. It is wierd why your GPU is idling with high clock speeds though. Even when it is not doing anything.

Game mode is a good feature (in theory) especially for people with lower end systems. Microsoft's marketing has been a little bit misleading, and they havent quite got it right just yet. But it is going to improve over time, I am sure. Not only are system recources dedicated and favoured towards any running game. In certain situations, code can be processed without having to go through the normal abstraction layers which naturally take up recourses. But like people have already said, you will only see the benefit of this on lower end systems. Microsoft also have the advantage that they can manipulate parts of the operating system that third party 'boost' software can't access. Love or hate Microsoft and Windows, there is one thing that cannot be argued. That they seriously know what they are doing when it comes to programming software. The Windows NT kernal that powers both Windows and the Xbox, has grown in functunality and features over the years, while reducing the amount of processing power that it needs to run. Windows runs on a million different combinations of hardware, that flexibility comes at the price of performance. They do not have that issue with a console as they know the specs of every single Xbox being sold. So software can be wrote with that in mind, giving extra performance. Game mode is partly about giving the performance benefits of a single spec'd machine, on a Platform that supports millions of combinations, They will never get it down to the level on consoles and they havent got it quite right at the moment. But it will get better. This is a good thing though, as it is going to bring more gamers to PC. Try and run a given game on a PC with the same spec as an Xbox one. The performance will be way lower on the PC than the Xbox, because of the streamlined paths consoles can use.
