What's the chance of buying a i5 4670K/4690K that will be a "bad" overclocker?

I've heard of people buying unlocked i5's and getting no OC's due to....some reasons.

What's the actual chance of this happening? Because if it does, I'd be so disappointed at wasting my money.

Is it quite a slim chance or...50/50 kinda thing?

The rule of thumb all the Mods say for OCing is: EVERY single system is UNIQUE. So even if you and your brother bought the EXACT same parts from the same exact same place, your results will ALWAYS be different. OCing is based NOT JUST on the CPU, but the capability of the Mobo, the RAM used, the quality and consistency of the PSU and Power in your area (dirty power adds many more issues to the calculations), the type and performance of your cooling system and THEN FINALLY how specifically that INDIVIDUAL i5 was manufactured. All these things lead to how 'much' or 'little' you can OC. Someone using Liquid Freon on a specific Mobo, matching RAM, PSU, and of course cooling system got a iCore to get over 25Ghz!!! Could they maintain that...
If you can't overclock at all you are doing it wrong. A bad overclocking 4670k is one that only gets to 4 or 4.1 ghz while a good is one that gets like 4.5 or 4.6 so there isn't a huge difference. I guess I would say it's like a 50% chance you get average and 50% chance you get good or bad?

There is a 50/50 chance. You may recieve one that doesnt overclock very well. You may not. There will always be ones that don't overclock very well. Now, that doesnt mean you can't overclock but it has a lower limit than other ones may have. Most people I have seen never really recieved one but I would go with a older Haswell cpu rather than a newer Refresh Haswell cpu. Either way, you won't be wasting any money if you cannot overclock like some others can. I think you will be fine with whatever cpu you wish to purchase that is unlocked :D

That's actually a very complicated question. The only way to answer it would be to get statistical information from Intel, or else do a study of several thousand K-chips that people have pushed very hard on an overclock.

There's also the fact that "good" and "bad" in this context aren't defined. My guess is that exposing a weakness in a chip's ability to overclock to an extreme point would require having a high end cooling solution, power supply, and motherboard in the first place - then trying to push for speeds on overclocking fora.

If that were your goal, the odds of getting a "bad" chip are easy to get around anyway. Just buy 5 of them, overclock them all as much as possible, and then return 4 of them within a week - done. The best wins a spot in your computer. But if reaching the highest overclocks possible isn't your goal, (as Jcomptech said) any K-chip will be as good as the next one. You'll be good with any chip that works. Just assess your goals.

Could they maintain that? Only for testing purposes then of course shut down, not for game play. Yet I seen plenty of posts of people spending $2000-3000 for a system and the most they can eek out OC (as noted) was 4.6Ghz semi consistantly, and would have to lower down when playing some games or shut off OC when NOT playing, in order NOT to kill the CPU/RAM.

Remember OC is burning out your CPU faster (burning both ends of a candle) then the manufacturer guarantees it's performance / lifecycle will last under normal (40 hours a week 5 days a week) usage. More then one person 12 months later had to buy a new CPU because they kept pushing the OCing all the time, and well killed the life of the CPU that fast.
