Hello
My pc
Gtx 1080ti
16gb ddr 4
I7 6700k

After upgrade to a 4K screen.
Do I need to put more mony for the 8700k with new z370 motherboard (600$) ? Will it make any diffrance
Or just stay with the 6700k ?


The only thing my pc is doin and will do is gaming at ultra 1440&4k!!
 
Solution
No, your cpu is fine. The higher the resolution the lower the FPS and the less the work for the cpu. Ok that’s over simplified but it reasonably describes it.
