Well i just change my fx 8350 to i5 4690k. And now i know when i buy amd that was very bad decision.   
For games like crisis 3, battlefield 4 or watch dogs, 8 cores are good.   
But for sim games like DCS or ARMA 3 it is very bad. I mean its unplayable compared to intel.   
amd fps = 33 (42.ghz stock) 
amd fps = 37 (4.9 ghz)   
intel fps = 52 stock speeds   
I thought that it will be maybe 10 fps diffrence only but the change is ridiculous.   
So if anybody have amd and trying to play dcs 
 i sugest to sell it as fast as possible.
