I'd take it back to Ivy-Bridge, or even Sandy-Bridge, there's many whom still use them.
Just looking at all those red Haswells, especially the i7's I find misleading. My 3770k never goes past 55%, my gtx970 never gets past 63% unless I drop a 4k DSR. So since the i7-4790k is bright cherry red, it must mean my 3770k is being bottlenecked by everything. Yet I'm still way beyond 60fps in everything I play, and can still get 300fps in CS:GO. Granted I'm not playing BF1 or gta5 or Witcher 3, so maybe a little clarification as to the boundaries might be warranted. With a 970 basically not much different to a 1060/3Gb, 1080p isn't much of an issue to most games, only the uber new and intense graphical/cpu monsters. Even at ultra, gta5 should be getting 60-80fps on average at 1080p. And that's what ppl will be concerned with.
Maybe I'm getting too deep into it, but saying that i7 is going to 'bottleneck everything' is gonna freak ppl out. Especially when there's a hundred+ posts telling ppl to go ahead and wait, they don't need to upgrade, the i7-4790k is still a very good cpu that's really just as good as the i5-8600k for most things.
For AMD, the Ryzens have equitable IPC to Haswells, so on anything 4c/8t or less, a Ryzen 5 1600 should run roughly equitable to a i7-4790k, yet a Ryzen 5 16xx is magenta, only bottlenecked in extremes, but the i7-4790k is red, bottlenecked by everything... Now I'm really confused.
