At that price the 5600X doesn't seem very competitive. Particularly vs. something like a 10600k @5ghz+ as the IPC gains would disappear due to lower clock speeds. You get an iGPU in the 10600k also ofcourse.
Yeah and you need z490 for max mem speed and overclocking, you can fire the 5600X any cheap B550 and get max performance out the box with with mem and CPU overclocking, oh and PCI-E 4. 10600K is a bad buy come nov 5th.
