OK latest update i managed to get my CPU stable at 4.3 GHz with 1.25V and 60 C temp and woohoo 120 FPS now i am satisfied.
How do you overclock the CPU to 4.3 GHz if the Max Turbo Frequency is 3.6 GHz?

Probably I don't understand how overclocking works 
Overclocking is done in the computers BIOS, witch you can acess while booting. It is a matter of tweaking the number of Ghz the CPU will run at. Usually the manufacturer set it lower to provide stabillity and to produce less heat.
You can however run CPU's stable on a higher clockspeed than factory, by increasing the amount of voltage delivered to the CPU, there by allowing it to run stable. This will also produce more heat, and there by requireing a better cooling solution.
I have a i7 5820k running at 4,5 Ghz stable, but the highest achiveable overclock will vary from chip to chip.
I wouldnt recommend overclocking if you do not know what you are doing, as it can lead to a ruined processor.
