Should I buy a NEW I5 6600k and overclock (about 4.3 -4.4 ghz) or a non k i7 6700 used? Mostly for gaming and some photoshop. The i7 is about £10 cheaper.

The i7 has HT enabled on it which gives it 8 threads out of the 4 cores. The i5 is more of a 4 core 4 thread processor part. The i7 can't be overclocked while the i5 can. If all you're doing is gaming, then you'll be fine with the i5. Mind you, if you go for the i5, you're going to need DDR4-3200MHz since you will naturally need to go with a Z170 board which can overclock the ram as well as the processor. If you go for the i7 you will only need to go with a B150 chipset board and DDR-2133MHz rams.

If you don't already have the motherboard you can buy a i3-8350k (4 core and 4 threads like the 6600k and unlocked for overclocking) and overclock it

It is not widely available just yet and so those few samples out there are likely to be slow to ship and overpriced. Also the motherboard (and likely the ram) is going to be more costly. Waiting on coffeelake might be the way to go though.

In order to drop in a Kabylake processor part you're going to need to update the BIOS on a Z170 chipset board with a Skylake processor part prior to dropping in the Kabylake part unless we're dealing with the cream of the crop boards from Asus/ROG with their BIOS flashback tool.

Just to clarify, I already own a z170 board. It was on sale for 49.99 so I just bought it! My PSU is a bit poor (cx500). Atm, I'm leaning toward the i5.

If you have the requisite update for your Z170 motherboard, a I5-7600K should cost the same as a 6600k and be able to oc a bit better. Typically to 4.9 vs. 4.6
For gaming, the single thread performance will be more important than the number of threads past 4.
Ram speed is not usually important for gaming.

I'm seeing a lot of old-schoolers talking about single-thread performance being better for gaming. Skylake is plenty fast single-core already without overclock to keep up with any GPU; except if it lacks the multi-thread ability. It's the new multi-threaded games that the quad-core i5 lacks the multi-core performance to keep mid/high-end GPUs fed.
Just watch this i5-8400 (6-core) vs i3-8350K (quad-core) comparison video. The i5-8400 is mostly winning, and sometimes by a large margin. The 8350K wins some, but when it does it is a small margin of difference. https://www.youtube.com/watch?v=fGC2Oh7cPeQ
It largely depends on the game; but any game that is mostly single-threaded will run well enough anyway.
