I5 2500k Overclocking for Gaming.

I'm planning on building my own PC soon and within that process I'd like to learn everything I need to build a safe PC [I'm not that much of a novice] But I know there's still a lot to learn before I can start selling my Custom built PC's.

I know that you can overclock the i5 2500k to 5Ghz at max with a really good cooler or even Liquid cooling. Unfortunately I won't have the money to buy a really good Cooler and therefore I will have to stick with the Hyper 212 .

So my question is , If the PC I'm planning to build was mainly for Gaming (Around 2-3 Hours in a row) a day and some photoshop and Video editing too , then what would be the maximum clock I can take my CPU to with the Hyper 212 & a Corsair CX600 PSU baring in mind it will be a gaming intensive PC

EXTRA QUESTION :

So the current PC I have which I bought almost 2 years ago (Big mistake // will never buy a PC from someone else again) Isn't capable of Overclocking my current CPU (Phenom II X4 945 3.0Ghz) @15%. The seller told me it was 100% Safe to have it clocked by an extra 15% but It became obvious it wasn't when I started to get bluescreens while playing Crysis 2. I am using a Crappy/stock CPU cooler too. So what could the problem be? Was he terribly wrong? Or is the cooler simply not good enough? Also I did change the Thermal paste on the CPU, still no help.

Did you increase the voltage at all?

And if you are overclocking on air then go with an i5-3570k instead of the i5-2500k.

I don't actually know how you increase the voltage. So whether he did or not I'm not sure. If you could briefly tell me how I'll let you know. Sorry for my newbiness.

As for the i5 3570k I've been told by many if I wanted to OC then the i5 2500k is better?

The 3570k gets hotter than the 2500k when voltage is increased for overclocks, so you will be able to get a better overclock on the 2500k, but remember that the 3570k @ 4.5ghz is roughly equivalent to a 2500k @ 4.8 or 4.9 ghz. So unless you are going with a powerful liquid cooling loop then the 3570k is a better choice.
 
4.5 on a 2500K is a safe bet. That's pretty much the standard OC for a 2500K with a 212 Evo.

Depending on the voltage required, room temp, case airflow, and how well you mount the 212 Evo, you may be able to go higher than 4.5, as well. I'd say, with the best of all scenarios, you'll top out at 4.7-4.8 on a 2500K with a 212 Evo.

With the 3570K, it would probably top out at around 4.3 with the 212 Evo. Ivy CPU's just run extremely hot, when OC'd.

You need a lot more than a 212 Evo to get to 4.5 on a 3570K.

I can stress enough how much you should read the intel/i5 overclocking sticky thread guides in this forum. the 2500k will almost always overclock to 4ghz on its default voltage.

Be careful that the motherboard doesnt just keep ramping up the voltage as you up the multiplier. You need to set that stuff your self :)

Anything over 4.3/4.4 isnt going to give you any real extra performance in games anyway, and should be fine with your cooler. The rest is just for bragging rights (which is reason enough to try for more).
 
I would expect that most people would have a hard time getting past 4.3GHz (about the point you have to start upping the voltage) on the Intel® Core™ i5-3570K with the Cooler Master Hyper 212. Heck with the Corsair H100 I sit at 4.3GHZ for a 24/7 overclock.

Are you in push/pull? What kind of airflow does your case offer? A 4.3 with an H100 seems a little weird to me, there must be a problem somewhere there because I have mine (same cpu same cooler) at 4.7 with temperature room ahead if I wanted.

I got a Kuhler H620 for my i5-3570k, and it runs stable at 4.6 easy around 60C max load temps.

Definitely love how powerful it is. 7.5 in Cinebench, crushing it. My old 965 BE OC'ed to 3.88 wouldn't hit 4.5.
