are you talking from personal experience?11th gen doesn’t OC as well in fact it loses to a 10900k so pointless upgrading to an 11700k.
OC the 10600k for now, upgrade the gpu first and then start saving for AM5 would be my recommendation.
because my 11700kf did 5.2Ghz, with a ring oc and 4400mhz ram that would put it faster than the 10600k GN just used?
