Upgrading from i5-2500k

Hey guys,

Im currently running with an i5-2500k @ 4.2ghz in my gaming set up.

I was just wondering if anyone could give me some informed advice on whether its worth dropping ~£250 on an i5-4690k + motherboard? What sort of increase in gaming performance could I expect to see?

Cheers,
Gall
