Need to replace my gaming rig - which CPU?

[Arterion]

Hi all,

It seems building a new machine these days is a bit of a can-of-worms, when it comes to deciding on specific components. I'm coming from an i5-2500K, and I'm not especially bothered about overclockability. This new rig will primarily be for gaming, with an R9 390 and I'm torn between the following CPUs:

i5-6600 3.3GHz @ £169.99
i5-6600K 3.9GHz @ £229.99
i7-6700 3.4GHz @ £249.99

There's larger leap in price from the 6600 to the 6600K, but unsure what the performance difference is like?

Would appreciate any advice!

There's about 7% power difference between the two 6600 chips, but the K series is unlocked so will allow you to overclock; where the non-K is not.

To what extent will that ~7% difference be felt in games, do you think?

Might end up going multi-gpu somewhere along the line, but certainly no plans in the short-medium term.

Thought about the 5i20k ?

Nope. Should I?

Overclock your Core i5 2500K??

The motherboard is on its way out, doesn't make sense to fork out money for old tech.

5820 all the way.

I'll never go back to a quad core chip.

Why?
