Overclocking, is it a necessity? (i5 4670/4670k)

I plan to buy a Haswell chip, and I have decided to buy the i5 4670k since I have read that it is unlocked for overclocking.

But, I still haven't got a clear answer to this question, do you really need to overclock?
Would you notice a very big difference in speed in your overall tasks? Or would it only matter in specific types of tasks?

I play regular "gamer" games.
I don't mind the price difference, but if there really is no "significant" difference, maybe I'd just go with the non-k.

Other components of my planned rig:
Mb: MSi Z87GD-65 (Gaming)
Vidcard: MSi GTX 760 TF 2GDDR5 (Gaming)
HDD&SDD: 1TB and 128GB
RAM: 8GB
*Cooling: corsair h100i (*only if I get a 4670k)
OS: Win7 64bit

No you don't need water cooling for just a mild overclock. To keep things in perspective, I have an i5-3570 OC'd to 4.2Ghz, and it doesn't even hit 60c in gaming on a cheap Cooler Master 212 EVO cooler with very low 800rpm fan silent setting. Haswell's do run a bit hotter, but at max 4.0-4.2Ghz, it should still run fine on air.


LOL. I know what you mean by "the urge to tweak" :D Just because you get a K chip doesn't mean...

You don't need to OC no. It's generally fast enough for most games, though if the price difference is minimal, it might be useful to have a 20% overhead in the future with the K chip. Non-K chips can only reach +200-400MHz on Haswell's unlike their Ivy / Sandy predecessors (which had +600-800MHz), so the performance gap between 4670K vs 4670(non-K) is greater on Haswell than 3570K vs 3570 (non-K) - but the price difference isn't. They're not as good value as they used to be, so you might as well just get the K chip.

Thank you. So now I've decided to buy the 4670k. Just for future proofing.
Would overclocking it until about 4.5GHz cause an easier wearing down of it? Because if it would break down more easily there wouldn't be much sense in my planned "future proofing" is there? Lol. I plan to at least keep it for about 3 years before I decide to replace it. Do you guys have any suggested "safe" overclocking level, like for example until 4.0GHz or 4.2?

Thanks guys

Haswell's do run hotter than older Ivy Bridge's (but are around 10% more efficient). You could certainly aim for say 4.2GHz as a fairly safe mild OC (which is still 800MHz above stock speed / a 23.5% speed boost) without temps getting too high.

So I wouldn't really need a Corsair h100i anymore do I? Or do you think it still is recommended for longevity of the CPU?

I really have a problem in always trying to get the "maximum" performance when I can actually buy a cheaper one and save some money instead. Well, that's why I'm here asking for advice.

Thanks again!

I suggest a different strategy.
Get the unlocked CPU and suitable OC friendly motherboard and install a cheap aftermarket cooler-the little Hyper 212 Evo is popular-because most OEM coolers are, frankly barely good enough but don't overclock yet. Instead wait a couple of years then OC it and possibly add a better cooler/GPU it's a great way to breathe new life into a flagging system ;).

LOL. I know what you mean by "the urge to tweak" :D Just because you get a K chip doesn't mean you have to push it to extremes, you could always do a mild OC, and treat what's left as a future reserves that may make the difference between an extra year's "gaming life" 2 years down the line.

Thanks for all your tips guys, now I've decided not to buy a corsair h100i, and opt to buy something similar to the cm hyper 212 evo.
Gosh, I can't believe I thought of buying something so expensive. Well, it was what was holding me back.
I could get the money now but I'd forever be bugged by the feeling that "maybe I could have bought something cheaper"

Any other suggestions for the cooler? Something maybe a tiny bit better than the evo? The store I'm purchasing most of my components doesn't have one. So maybe you guys have other suggestions?

Maybe something in Noctua? Or Deepcool? Or other cooler master?

Noctua are probably the best you have mentioned.
Look for a 120 m.m. fan, smaller fans don't cool as well and some larger coolers block or interfere with the memory modules but if you take a note of those for sale and Google for reviews you should avoid any problems.
Be aware, not all cases will accept tall coolers and some do not come with a fan, a minor annoyance but one that can be avoided.
Online shopping will give a broader choice.

I've read on newegg about the cooler master geminii s524 and it seems it really is a big cooler according to some. I plan on getting a Corsair 500R so I think it's big enough for it, but I'm afraid it'd block the memory modules as you said. Some said to just rotate them so it'd fit. So I think I'm going with that.

Thank you guys
