1. Yes, in fact I did. I'm really not sure who you think you are to tell me what I can and can't perceive but whatever.
2. The 8700k Turbo's up to 4.7GHz on a single core, for 6 cores it only turbo's up to 4.3GHz I did not down-clock anything. WoW still utilizes 4 cores even though it does not do it well. The fact that you didn't know that explains a lot.
3. Yes I am talking about WoW, you are correct in your assumption that I would not be able to tell the difference in other games between an 8700k and 2700x, i'm not arguing that. For WoW in particular, yes I would. In fact, for almost all my games I could tell no difference between my 6700k and 8700k, even though there is roughly a 50% difference in RealBench scores between them. However, in WoW, and even SCII in particular, there is a very noticeable difference favoring the OC'd 6700k.
4. I most definitely did notice. Since WoW is single-core for the most part, that 400MHz actual turned out to be about a 10-15fps difference in heavy areas. In Max CPU usage areas the difference was a couple fps, but I don't think anyone would call 10-12 a "couple" frames difference. For WoW I would say there is a 1-2fps (avg) difference per 100MHz for Single core performance.
5. Almost anyone who has played at 100/120/144Hz can definitely tell you in most cases you can tell an fps drop below a certain point. I will cede the difference between 50-60fps is perceptively far greater than 90-100, I personally don't notice a drop from 100 until about 85 fps. As far as the smoothness threshold, that is unproven science and is far more likely to differ from person to person rather than a default value for every human on earth. So stating that any one person can only perceive up to 60fps, and past that there is no discernible difference is blatantly wrong.
6. The 6700k 4-core turbo speed is 4.2GHz, the 7700k 4-core boost is between 4.2-4.4GHz (I can't quite remember I know the other two from experience) and the 8700k 6 core boost is 4.3GHz. Being within 100MHz they are only going to show a few fps difference, you are correct. But a 400MHz difference will be far more noticeable. As would the 700MHz difference between an 8700k @5.0GHz and a 2700x @4.3GHz, which seem to be where most benchmarks put them at.
7. Again, some people's eyes (rather their brains) are capable of processing information (such as sensory information) faster than others, which would allow people to perceive small changes in fps. There is nothing anecdotal about that. It's not my fault you don't believe me. Some people can see an fps difference of 10fps even from 90-100fps. I most certainly could tell the difference between mid 80's where I was with my 6700k to the low 70's with my 8700k on WoW. In fact, it is an adjustment for me going from 100Hz to 60Hz (where some of my games are capped in the code and unlocking it brings up glitches) It takes me about an hour to get used to Skyrim (60Hz) coming from playing at 100Hz. And in fact, Skyrim looks clunky even at 60Hz until my eyes get used to it, then it looks fine after that. So unless I am some kind of sensory wizard, I know other people have and will experience this as well.
8. This conversation has gone far enough off topic, and I will not be taking part of this nonsensical, pointless, argument any longer.
The fact is, there IS a difference on fps based on clock speeds in WoW in particular. If he were playing at 60Hz either CPU would make no difference as both are capable of being 60fps+ 95% of the time. At 100Hz there is a difference. That's based on the fact I have about 2 months of playtime each on both a 6700k and 8700k at 3440x1440 100Hz, same settings, various situations, using RTSS the entire time.
You can choose to believe it or not that's up to you. Until you see for yourself you won't believe it. That's fine. But I will no longer be taking part of this off-topic bickering here any more.
I'm unfollowing the post just so I won't be tempted to argue any further.
