Yes, an overclocked chip from the same generation will obviously beat a stock clocked i7. A stock i5 and stock i7 are neck and neck in gaming in 99.9% of cases, and the difference between them is within the margin of error. Disable hyperthreading on the i7 and you've got an i5 with a different name. Overclock an i7 with or without HT enabled, and you've got an i5 with 4 more cores (logically)..
Also, K doesn't mean the chip is built to handle overclocking. It simply implies it's unlocked and doesn't give any guarantee of any clock speed above stock. Of course, all of them can clock somewhat, but not all of them are great at it. HT does affect voltage required for clocking, as well as temperatures, but it doesn't affect how well the chip itself will clock.
Also, the point you made is somewhat void, since it's only ~£15 difference between a 2500 and a 2500K, and likewise with the 2600 and 2600K. So, to correct you, "Not overclocking your K series chip means you are wasting £15".
