Should i leave Global C-States Disabled by default?

I would recommend you do 'powercfg -restoredefaultschemes' in elevated CMD and choose High/Ultimate performance plan, and leave it as it is.

read my last post,no chance in hell.

Well, my friend, believe it or not, doing what I suggested gives you High/Ultimate performance (with both having min. + max. 100% by default) and exactly what you just posted previously. So what exactly had no chance in hell of happening for you, considering it is already done?

you did not read anything when i load up a new power plan via cmd command min proc state is 0%,when i did it to 100% it is way better for me like a user above sugested to me,so you are saying that i must not to that and play with default power plan wich is min proc 0%,as i said i played cs2 match and is ulta bad,so no chance in hell i will play with default power plan ,i will at least change min proc from 0 to 100%.so bassicly a default ultimate power plan fresh new but with one changefor now.

I just told you that High/Ultimate performance has a default state of 100% for minimum and maximum. If your power plans do not have that set to default, that means you've either modified your power plans or you're not using High/Ultimate. We can see from your posts that you've done some testing with various plans and different settings-- hence why I'm suggesting you use 'powercfg -restoredefaultschemes' in an elevated CMD to make sure that you've cleared everything and get a proper power plan.

Conclusively; you will yield the best performance and stability from resetting your plans and utilize the High (or Ultimate, if your system has it) performance plan. Give it a try, and you will see that the min./max. is 100% by default With that said, you do you

On my system, the "High Peformance" Windows power profile uses "100%" for "Minimum processor state."

I don't know if the power profiles are edited when installing chipset drivers though.

Disabling C-States is not recommended, only for testing purposes, or there is an issue and it could indeed help.
The DEMOTE and PROMOTE at 99 makes them work with very light load, but disables them with a bit of load or running games.
The IDLECHECK 1000 helps both disable and enable states.
These settings are what I use with a batch file.

Disable:
powercfg /setacvalueindex scheme_current sub_processor IDLEDEMOTE 99
powercfg /setacvalueindex scheme_current sub_processor IDLEPROMOTE 99
powercfg /setacvalueindex scheme_current sub_processor IDLESTATEMAX 1
powercfg /setacvalueindex scheme_current sub_processor IDLECHECK 1000
powercfg /setactive scheme_current

Enable:
powercfg /setacvalueindex scheme_current sub_processor IDLEDEMOTE 40
powercfg /setacvalueindex scheme_current sub_processor IDLEPROMOTE 60
powercfg /setacvalueindex scheme_current sub_processor IDLESTATEMAX 0
powercfg /setacvalueindex scheme_current sub_processor IDLECHECK 1000
powercfg /setactive scheme_current

I have an old I7-4790K, running at 4.6GHz at a fixed frequency (SpeedStep disabled).
CPU voltage doesn't increase power usage, C-States disabled do.
I use Windows power plan 'High Performance' 24/7.
