Hello community!)

I'll try to be short, so here I have some questions, that I can't resolve definitly to myself.

My old LGA775 system is dead by now, so I'm trying to choose something for 1,5 - 2 years.
Though about LGA 2011-3, but things are I don't have enough money and I won't need 8-core Intel HEDT by now.

So I've decided to myself to buy something in range high-end i5. (100$ is too much for for "i5 with HT@i7", AMD CPUs are very hot and old in terms of technologies).

So I've ended up right here - 4670 vs 4670K vs 4690\4690K.

So, the first thing I'm interested in: We all know that Haswell are having veeery major problem with OC. But that's not all the problem: I assume that low-quality thermal grease will wither with time. So 4.2 GHz now - lower than 3.4 after. Am I right?

And does K CPU worth it? In terms of gaming perfomance? After all, will 4670K be better at 4.2 than 4670 with 3.8 in turboboost? Maybe because of awfull OC 4670K isn't much faster than 4670...

So, I'm not the fan of overclocking, but not against of having some additional perfomance for myself. Especially with open multipler.

Second thing - I think many people know, that some MB on H chipset could help with overclocking K processors. For example, ASRock H87 Fatality.

So, is there some "invisible" cons about Z87 mothreboards, exept PCI-e lanes? Maybe...... quality? Here I assume, that maybe H87 allows overclocking, but not for a long time.. not just like Z87


So - what do you think? 4670K + Z87 vs 4690 + H87 vs 4690K + Z97 (If Intel if they deign to change that sh*t under the CPU cap)

P.S. Buying only CPU+MB, budget is free of limit, but within "reasonability"

i would recommend ivy bridge cuz haswell hates ram with voltage over 1.575 volts,

Haswell does not need fast ram over 1.5v.

With your budget, I think i5-4670K and a Z87 based motherboard is appropriate.
The extra 5% more you pay for a "K" will get you 20% more performance.

Haswell overclocking is actually good until you get to high voltage levels.
4.2-4.4 can be expected with air cooling. More if you get a golden chip.
The socket 2011 motherboards will be more expensive.
Few games can use more than 2-3 cores so the 6 core offerings will not help, nor will the extra hyperthreads.

Some H87 motherboards say they permit cpu overclocking. I would not count on that. Intel is not happy about it, and may find the means to shut it down.

Well, anyway I'm against of overclocked RAM - always trying to take just usual.

Well, that's thing I was interested in . Even if non-K CPUs could overclock by bus, just like IB and SB.....that's not a variant. I've just killed my previous platform by using bus OC.
So, this is good news for me :D

Now having Zalman CNPS10X. Thinking of buying Corsair H90 - for some reasons I want exactly mid-range priced water cooling. So, I thing cooling system isn't an issue

Having in mind ASUS Hero and ASRock Killer. KIller is about 40$ cheaper. Is there some advantages in Hero?

P.S. I have always taken Asus, but now, foe me ASRock is more that reasonable. Especcialy on my market.

We all know that? It's news to me lol. Anyways, low-quality thermal grease, what are you talking about? If you are referring to under the ICS it isn't "low-quality", it's the same as any other. And no it won't "wither" over time. Obviously no one can guarantee you any particular over clock but you're fine.

"And does K CPU worth it? In terms of gaming perfomance? After all, will 4670K be better at 4.2 than 4670 with 3.8 in turboboost? Maybe because of awfull OC 4670K isn't much faster than 4670..."

No one can tell you whether it is worth it for you or not. I have no idea what your financial situation is. As for awful OC, I'm not sure what you mean. Performance wise, 4.2 is 4.2. And yes obviously 4.2 is faster than 3.8.

"P.S. Buying only CPU+MB, budget is free of limit, but within "reasonability"

That tells me nothing at all about what your budget is so of course it is impossible to tell you what to get.

I'm having first records (Guarantee blanks) of massive returns Ivy CPU's, because of overheating. non K CPU's are among them. And what's more - some of them weren't "heavily used" - that's for the users we know personally. And IB had some problems with heating - there's no solder between chip and cap since Sandy.

What's about withering - I didn't state that, just assuming.

Ok, budget is near 550-600$ MAX.

About clocks - if top overclocking 4670K on air gives less than +5-8% of perfomance, comparing with 4670 - that does mean that K+Z87 is not worth it to me. Maybe, if it gives more than +10% - it has some sence..

I'm not really sure what you're saying here. Are you saying you heard of massive returns of chips? That would be the first I have heard of it. In any case as for the haswell chips, since that is what we're talking about, intel puts grease on chips with a tdp lower than 95. They use solder on 95 and up. Haswell as LESS heat to dissipate, not more. Hence no need for the solder.

"Ok, budget is near 550-600$ MAX"

Well that is 4770k money.

"About clocks - if top overclocking 4670K on air gives less than +5-8% of perfomance, comparing with 4670 - that does mean that K+Z87 is not worth it to me. Maybe, if it gives more than +10% - it has some sence.."
The 4670k is like 15 dollars more. Either CPU is WAY under budget so why not get the K?

About K CPU - yes, I just was thinking about it. I'll go with K version. Anyway, it's much more comfortable to have overclockable CPU. For any reasons.

4770K isn't worth it - these platfrom is only for gaming, for nearby year. I have another plans to do, and these purchase is only for replacing old platform. And, of course, I'm trying to save some funds :D
