Is the i7-7700K still worth buying?

For an existing 200-series build it is a solid, fast quad-core. For a new build, newer six- and eight-core CPUs offer more for heavy multitasking.

Does it come with a cooler?

No. It is sold without a cooler, and its 91W TDP means you should budget for a decent air or liquid cooler.

It uses the LGA1151 socket on 100- and 200-series chipsets. It does not work in 300-series or later boards despite the same socket shape.

Yes. The K suffix means an unlocked multiplier, so you can overclock on a Z170 or Z270 board.

The i7-7700K adds hyper-threading for 8 threads and a higher clock, giving it an edge in games and multitasking at a higher TDP.
