Cheapest i7 with socket 1150?

I know I know, counter intuitive, no such thing as a cheap i7.
But humour me.
My current cpu is an i5 4670k which i think is socket 1150, so im simply looking for an i7 of the same socket type and will give good enough performance to not bottleneck my 1080 as my i5 is currently doing.
Looking for around £250-£300 range

For Gaming you are not going to get much better performance out of an I7. You are better off overclocking your 4670. You should be able to go from 3.8Ghz to atleast 4.4 with just a decent air cooler on the CPU. That would give you near a 15% increase and the same clock as a 4790K and they go for $250 Plus on ebay.
 
You are not likely to solve your problem with a I7-4790K that is the strongest I7 for lga1150.
Your I5-4670K has 4 threads and a stock clock of 3.4.
Most games can use only 2-3 threads, so the added hyperthreads of a I7 will not be very useful.
What will be most important is a higher clock rate.
If you have an overclock capable z-- motherboard, you can overclock your I5-4670K to somewhere in the 4.0 range.
Or, as an alternative, a I7-4790k has a stock clock of 4.0 and can perhaps OC higher.

Any lesser I7 chips will not have a clock speed any better than what you now have.

And... it seems that the current lga1150 processor prices are rising as the supply of new chips dwindles.

Better to look at kaby lake and a new motherboard.

That may change over the next few months as the market adjusts to AMD's Ryzen series. The real fun should begin next month with the R5's launch. At that point, we'll likely see a bunch of re-benches to show how much progress the ecosystem has made with supporting Ryzen since the R7's launch.

I cant imagine what else it might be.
Cpu - i5 5670k
ram - 16gb hyperx
mobo- msi sli krait edition
psu - rm 750

The only weak point in my system seems to be the i5 tbh, so I'm just presuming it's bottlenecking the 1080 tbh

If an overclocked i5-4670k is really bottlenecking your games, then unless your games are one of the few that show performance scaling beyond 4C4T (there is maybe a dozen of those at the moment), the i7 won't help you much.

For example in battlefield 1.
I have 16gb of ram, i5 4670k gtx 1080. But at 1080p on ultra settings I get between 70-90fps.
My friend has 8gb of ram, an i7 6700 and a gtx 1070 but gets about 100.
I turned up resolution scale to 135% and didnt see a drop in fps at all, so can only presume something is bottlenecking the gpu. The only difference whereby im at a downgrade between my and my buddy's system is the cpu.

Drivers are all up-to-date, resolution is 1080p and game that i've checked and is really underperforming is an average of about 70-80fps in bf1 on ultra @ 1080p, whereas others who've benchmarked it seem to be getting 120-130fps. So yeah, quite a substantial difference.
Tested the gpu on unigine heaven and is peforming as well as a normal 1080 should, so it's not the gpu.
