Just to expand on this, 6700k vs 9900k (both @ 5Ghz) will vary depending on games in terms of a bottleneck on a 2070 or 2080. For instance, OP plays @ 1440p so the gap will be about 1-10% depending. Got to factor in cost as well. Is 10%'ish worth having to buy a new motherboard, CPU, and possibly faster ram? It can easily add up to $1K for 10%.
