There is a deal in my local store and the i7 is only £20 more, so I am wondering if the i7 is more powerful and would be better to overclock with.
Any help will be much appreciated!
Hello there! I reccommend that you go with the newer 1150 platform and the i5-4670K. You get many new features with the new platform which you will not get with the older 6 and 7 series chipsets:
Power savings
Better Integrated GPU(does not really apply for your purpose)
Support for faster RAM
6 Sata 3 6Gb/s ports
Option to upgrade in the future
Hyper threading in the i7 2600K does improve perofrmance in video editing and other CPU intensive tasks by a bit, but IMO the i5 is still a better option.
I personally still have a 2700K and it has been working great for me, but getting a 2 year old CPU right now is not a good idea IMO. On the Intel website its status is listed as "End of Life".
If you are going to overclock I reccomend that you get the Intel Performance Tuning Protection Program which cover damage to your CPU caused by overclocking for a very low price: http://click.intel.com/tuningplan/
Good luck and let me know if you have any more questions!

per core performance is better on haswell since it's a new architecture, also smaller transistors 22nm. i7 will only be useful if you need hyperthreading, and it will overclock better but not scale as well, a 5ghz sandybridge is like a 4.5 Ghz haswell quadcore.
Haswell is socket 1150.
Overclocking wise, what trop said. However, if you need the extra cores, go for it! The 2600k is a fantastic cpu, can do almost anything, even today.
thanks guys, i wont be doing that much stuff requiring hyperthreading so I think I will go for the i5 haswell cpu. Mostly I will be gaming, if anyone wants to know out of interest the gpu I am pairing it up with is a gtx780 directcu2.
Good luck! That is going to be an awesome build.
The new DirectCU cooler looks really cool!(But I like the MSI Twin Frozr design better!)
