Yeah it's a BS...you're welcome

Look into Gigabyte’s Aero series of laptops. They are light and thin, decent battery life and awesome performance. 

The reason of why I ignored your spreadsheet is because you're only comparing specs - one of the main thing to look at when buying gaming laptop is cooling performance / thermals
 
Avoid Asus FX and GU502 - mediocre cooling. Also Asus laptops have poor QC+QA and warranty service in general so I tend to not choose them, even though some of their models are good (I would still recommend them but buy at your own risk)
 
G531 is decent but only i5-9300H for your budget
 
Suggest increasing budget for more options unless you're fine with lower end GPU

Y540 then. Just make sure the BIOS isn't 28WW or newer, otherwise roll back to older version

Yes (assuming that you didn't get a lemon)

Lower fan speed causing high temps, no more max fan feature

Don't waste your time with Apple's horrible support and clueless techs - just send it to Louis Rossmann in case of issues at Rossman Group. MUCH better quality of service and support - https://rossmanngroup.com/

We had one of those ATI cards... but I never did try that trick (I think? looong time ago XD ).

I hope mine doesn't have any problem :( and I am not planning to do that just in theory maybe some years later when this will useless I will try it out.
Thanks for the recommendation It seems a good youtube channel about pcb electronic.
I assume maybe the driver is the same. From my opinion it is more easy if in boot they just check all the component are working fine so if some of them die they can just ignore it. So with the OC card use the same driver but they have the component too. It seems more easy to do and more money efficient.
But this is just my opinion there a high chance I am stupid. :)
Sorry if you get me wrong. I am not saying me as a user know more about this. If I would than there wouldn't been this question about it. Also I think if you design a card with missing parts that isn't money orientated but if you just design the "best card" which is in this case the OC version you could sell that in a higher price and if you left out some component the card would be weaker and you can sell it cheaper. I think this is just a way to make us money cows. Because if you design two cards that would be expensive. But if you design the stronger card just a little modification would be enough and there is the "low tier" card.
 
 
I heard an old story that was happened when I was little. There was an AMD card and if you soldered a jumper wire for it you got much better performance because that was the only difference between that and a higher tier card.
 
Thanks all of you by the way I got a feeling about both side should it work or not. I am just an engineer student so I am not expert in electric or computer hardware.But I thought this is an interesting idea and I would like to know more about these.
 
If anybody have more information about the topic I would appreciate  that :)
 
Also ignore my English I hope you can understand it I am not very good with grammar.
