[So your point is that you don't mind keeping a CPU at 100C even on the most basic of overclocks and the most extensive of cooling setups? That sounds like a waste of money to me - expensive platform(much more so than the 4790K platform, BTW), expensive CPU, expensive cooler, and yet terrible temperatures. What's the point in spending half of your earnings on a PC and still have it throttle or run at bread toasting temps? I can understand the issue being on an old, unnecessarily extended platform like the FX, but on a new, expensive platform like X299? Definitely not a good bargain.
I'm not trying to say that 2066 is a good value (or not), just that we have evidence to suggest that, aside from throttling preventing high overclocks on
all of the cores (and you could easily run fewer cores at higher turbo frequencies, like it does at stock), high temperature readings don't seem to do any practical harm.
Back in ~2006 when Core2Duo hit the market, the wisdom of the day was to keep your CPU under 60c, or ideally, 50c, and many would spend excessive money chasing this arbitrary threshold. Fast forward a decade, and many of these same CPUs are running at 80-90c under dust-clogged stock coolers, and we're seeing the motherboards and power supplies dying of old age, with orphaned CPUs ending up on eBay still fully functional. So, although we know that lower temperatures improve leakage characteristics and slow electromigration in an absolute sense, I'd like to voice a bit of skepticism how much it matters in practice. I often see suggestions to throw tons of money at cooling on this forum which, if older chips are any indication, won't go toward any real gains.
That said, I'm largely of the opinion that AM4 is a better value than Intel's HEDT for most things, that 1151 is a good recommendation for someone who wants a highly stable and bug-free platform or has no need for high core counts (mostly 7700K and G4560) or wants to use a system without a discrete graphics card, and that 2011v3 and 2066 are a tough sell except for very niche uses, the 7740K doubly so.
