So if I buy a 4790K will it realy run at 4.4GHZ stock with turbo boost enabled?

I find it hard to believe that any CPU can run at 4.4ghz stock.

Or is it all dependent on quality of motherboard, vrm heatsinks and CPU cooler?

Like does the 4790K auto OC to 4.4 for gaming on the likes of Arma 3? Or is it better to disable turbo boost and manually OC it to 4.4

please clarify for me as I don't know how all of this works but how the heck can the 4790K even Turbo boost to 4.4 GHZ on a Stock cooler?

Do you all realize that 4.4 GHZ requires aftermarket cooler? or is it a case that it can do 4.4 BUT it will throttle back down to 4 unless there is proper cooling?

turbo boost only uses what spare heat and voltage headroom the CPU has to achieve the boost speeds. So the 4.4ghz boost advertised will not be constant or even consistent. Also turbo boost usually only boosts when less cores are used check this out:

If you want a 4.4ghz clock rate then overclocking is the only way to achieve this constantly and consistently. in fact you can overclock and have turbo boost enabled to further clock speeds (though less stable IMHO) when less cores are in use (ie 4.4ghz with boost speeds up to 4.6ghz when using 2 cores). Lastly as mention intel stock coolers stink so it would inhibit your turbo boost/overclock as well. If you want to overclock i suggest...

With a stock cooler you will not be able to go above stock speeds. Even so, you will be hitting 90c constantly. Intel has crap coolers.

At 98-100c the CPU is throttle back so technically you can overclock to 4.4ghz, but most likely it will downclock due to heat

If you want to overclock i suggest strongly you get a high end air cooler/closed loop water cooled system or even better an open loop water cooled setup.
