This still applies to the 3800x because the aside form the i9 9900k, the i9 9700k is gaming king.
I really needed to hear this.
But 1 last question. The video i linked is a guy with 2060 card and same processor gaining 25 more fps then i do.
Why? i put the same res as he do and i got no gains. Is it becasue i play on a 27'' screen? (2560x1440, 144hz, 1ms, FreeSync, 2xHDMI/DP, )
