I think PCs in general run better on four cores than on two, even if most apps themselves can't take advantage of them, although I think in the next 5 years most new games will take advantage of 8 threads. But otherwise, it's just good for multitasking.
I had an argument with one fellow on the internet regarding i7 being plenty for whatever I was doing in terms of core count. But streaming a show on one monitor while playing Overwatch was hitting 70%+ CPU usage, with all logical cores being 60-70% utilized consistently, with spikes up to 90%+.
That was on my i7-4770K to be specific, running 1080P on a 144hz monitor for Overwatch, and Crunchyroll for 1080P anime stream on the second monitor.
So some games combined with slight multitasking is already taxing the 4C/8T environment.
And how much multitasking are we really using? If I had to guess, I would say not much, on average. You might have some folks here and there using it, but regular users need something between two and four cores, just as you said. You have the OS, the software you're using, be it a game or not, plus everything that's running behind the scenes, including Windows ineficiencies, and that's it. But for some weird guy that spends his day on 7zip, more than 4 cores brings no extra power. This is the reason why, no matter how excited we might get with 10 cores (I would love one, even if for bragging rights only), our i5s are enough for what we do. Maybe in 5 years from now games will be multithreaded, but I'm not holding my breath: something similar was said 5 years ago, and here we are. At the end of the day, we still need improvement in per core performance.
Browsers are becoming better and better at using more cores... and we're all running tens of processes in the background, some of which fire interrupts on a CPU. More cores allows for more going on at the same time without interruptions. You can actually feel this moving to an eight-core FX-8350 from a quad core i5... those eight cores provide a somewhat smoother multi-tasking environment, despite each core being slower and the overall performance being lower.
Humans are simply sensitive to changes in timing - more cores and more threads reduces the variability in timing, which improves perceived performance.
Hum.... I don't know many people who share your opinion about FX-8350 vs i5. Anyway, we have been multitasking for a while, a least to some extent: OS, Word, anti-virus, browser. The question is: for this light multitasking, are we better off with several cores with poor performance/core, or with less cores but with great performance/core. Reviews and actual people generally prefer the later. As of browsers, great news that they are improving, but download/upload speed is by far the most important factor in users experience.
Download speed is fine for web browsing if you've got something faster than DSL. How much data exactly do you think you're consuming while browsing the web? Outside of streaming videos you won't use up a ton of bandwidth.
I know this is ANCIENT, but how the hell did you not realize that multi-core optimization was so bad only because nobody could afford greater than >4 core CPU's pre-Zen??? Modern games run freaking TERRIBLE now on 4c/4t i5's.
I believe you do, for the sweet spot is now around 4 cores, as I said before. The question is: do you believe that your experience will improve significantly if you mo to 6 or 8 cores? Probably not, unless you spend your day zipping files or rendering images.
They said the same thing about quad cores, and dual cores before that. AMD has to get on top of the curve, not behind it. They'll offer quad cores for more mainstream systems, and 8 for performance rigs. More for servers, and potentially less for low-power and/or low-cost.

No, nope, nej, and nein.I see (FEEL) tangible improvements in my computing ever since dropped 2 cores for 4.
And it looks like others below agree....
