Is the i7-7700K still worth buying?

Only at a low used price and only if you already own a 100- or 200-series LGA1151 board. A modern budget CPU is faster and cheaper per core for new builds.

Does it fit my motherboard?

It fits boards with the LGA1151 socket built for 6th and 7th gen chips, such as Z170, Z270, H110 and B250. It does not work in 300-series boards for 8th and 9th gen.

Does it come with a cooler?

No. This is a tray part, so you need to supply your own LGA1151 cooler rated for at least 91 W.

Yes, the multiplier is unlocked, but you need a Z170 or Z270 board and a capable cooler. Expect high temperatures past about 4.8 GHz.

Does it support Windows 11?

No. Intel does not list 7th gen Core chips as supported, so you would run Windows 10 or install Windows 11 unofficially.

What memory does it take?

DDR4-2133 or 2400, or DDR3L-1333/1600 on boards that use it, up to 64 GB.

Our take on the Intel 7th Generation Core i7-7700K Quad-Core 4.20GHz Processor

The Core i7-7700K is Intel's top Kaby Lake desktop chip: 4 cores, 8 threads, a 4.2 GHz base clock and 4.5 GHz turbo, unlocked for overclocking on LGA1151 boards. It was the fastest mainstream gaming CPU of 2017 and still handles everyday work and older games well. It is a tray part, so it ships without a cooler or retail box. No price was given for this listing, so compare it against current listings before buying.
