The i7-7700K is a Kaby Lake processor, and sees a handful of small improvements over its Skylake equivalent. Those higher clock speeds of 4.2 GHz are the most noticeable, and you can easily overclock to speeds of 5.0 GHz. There's also an upgrade to support hardware encoding and decoding of 4K H.265, but these bonuses are lost when you're using a discrete GPU.
The i7-7700K is for you if you're looking for high speeds and the newest hardware. £294 is the cheapest it's ever been on Amazon, and you're saving between £20-30 over what it's been for the past few months.
