The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

Set it up to 5ghz and it's the faster responsive cpu you'll work with. Even multi-threaded tasks get a boost of around 20%. Excellent CPU for the price. Runs hot, so get a good cooler. Had a CM 212 evo and it was just fin but 5GHZ asks for a bit more cooling to keep temperatures under 72C

— I switched to Ryzen 3600 and it feels much better multi-tasking, without stuttering or drops of performance. Don't care about 55 FPS drop in games where I already had +150 FPS on EPIC settings if compared to intel. Ryzen all the WAY!

Well... this is the best 4-core/8-thread CPU ever made, not counting the ill-advised (i.e., stupid) i7-7740X. That being said, at about $350 (USD), it was very shortly thereafter made virtually obsolete by AMD's new Ryzen 7 series (8-core/16-thread) processors. Sure, the 7700K still had the performance crown for single-core speed and overclocked frequency range, but it was hard to argue against 8-cores/16-threads for around the same or less money and Intel knew it. Fast forward just a few months and Intel rushed the release of its Coffee Lake (8th Gen Core Series) processors because AMD was simply putting too much pressure on them. Surprisingly, rather than feeling entirely alienated and exploited by Intel, many people welcomed the new processor lineup, topped by the 6-core/12-thread i7-8700K, and seem to have bought them in droves; "fanboyism" (and/or loss aversion) is still alive and well. Back to the 7700K, for what it is, it's pretty good, even if it's really just a 6700K with slightly increased clock speeds and identical IPC. In 2019, it's still an excellent processor, particularly for gaming. There are a select few modern core-heavy games that give it some trouble (i.e., they do better with 6-core or more CPUs), but they're few and far between at the moment. And when overclocked, it only gets better... and hotter (not in a good way). I managed to get mine for a halfway reasonable price, mostly out of curiosity (I think I had just bought a Ryzen 5 1600, too). I probably should have waited, but I don't think anyone really knew that Intel would release an new lineup so quickly. Regardless, I can quite easily get 5 GHz out of mine at less than 1.35V. It sure gets hot, though. I use a Noctua NH-D15 on mine, which does an admirable job cooling it, but the thermal density of these monolithic chips just makes them inherently hot. I may delid mine at some point, but I'm not sure yet.

I bought it in 2018 for $250. It's still rocks! It gives me even twice or more fps than my monitor refresh rate in the games. If you still have i7-7700K in Sep 2021 there is no point of upgrading.
