Question I'm having FPS loss after upgrading motherboard,ram,CPU

Dec 1, 2015
I upgrade from an old fx-6300 processor to a used i5-9600k , used z390 aorus pro wifi, and new ddr4 3000 mhz ram 16gb and being run in dual channel with xmp enabled.

With my old fx processor playing cyberpunk I was able to hit near 60 fps on low settings paired with my rx 580 8gb.

Now after having installed the better components I'm getting only 20 fps with the same settings enabled.

I did a fresh install of windows and updated to the newest GPU drivers.

I am stumped and cannot figure out why I'm getting much worse performance from a much better processor ?
