Worth it to upgrade from an i7-4820k to a faster quad core?

About 2 weeks ago I bought an i7-4820k for my motherboard. I'm thinking about selling my motherboard and i7-4820k and buying a new motherboard and a i7-4771. I can right now get the i7-4771 for $240 at a local electronics store near me and an Asus Hero motherboard for $200 at that same store. I will lose money in the process, around $40-50. Right now I'm runnng my i7-4820k's turbo at 3.9GHz synced on all cores and I would probably run it that way if I had an i7-4771. Gaming performance is most important to me and I'm not interested in an i7-4930k.
 
No. It isn't unlocked. Overclocking the 4820k will eclipse the slight performance edge the 4771 has and then some

Overclock it! Even if you stop at the point before you need to raise voltages, you'll get a nice gain

Leaving the vcore on Auto, increases the vcore anyways the higher the CPU frequency is set. I think I will settle on a 3.9GHz turbo synced to all cores with the vcore on offset mode. It's what my motherboard sets my CPU to anyways when I set my memory to the XMP setting. I tried 4.6GHz, but even at 1.28v, LLC on regular, it would error out on me during Intel Burn Test within 2 minutes, at core temps of 70c. I don't want to spend lots of time testing overclocks and I'm more of a set it up and forget it person.
 
Why you purchased an Ivy Bridge-E in the first place if now you want to sidegrade to a Haswell that was already available back when you made your purchase?

Well I was not sure if I would get a C2 revision motherboard if I went Haswell. I already had the motherboard for the Ivy Bridge-E.
 
Your chip has 10MB of L3 cache and same Turbo max clock speed. It's also unlocked so you can push it past 4Ghz easily.

If you ever need more throughput your board (unlike the one for Haswell) supports 6C/12T models. At best it's a sidegrade IMO.

So why did you go with socket 2011 if you had no interest in the hexcore models? The extra PCIe lanes for SLI really don't provide any practical performance increases over the x8/x8 options available on the Z87 lineup.
 
Since I got my 4820k for only $250 + tax, I might consider selling it and upgrading to a 4930k. Will I be able to turbo boost all cores to 3.9GHz on the 4930k without overheating issues on Auto vcore if I use a Hyper 212 EVO with dual fans?
 
Also if I won't be able to turbo boost all cores to 3.9GHz on the 4930k without stability or overheating problems then I will stick with my 4820k.

I still don't understand the issue with turbo per cores. Every asus motherboard i've owned would let me force every single core to whatever speed I wanted - I never had a situation where core 1 was speed A and core 2 was speed B. Is this a motherboard issue, perhaps?

Asus motherboards will "synchronize" the turbo across all cores, ie if you overclock to 4.4ghz you will get that on every core if you specify in the BIOS. This thing about different per core turbo speeds is very strange to me, sounds like perhaps a BIOS issue with your motherboard.

Not sure on the temp issues though. What cooler were you using, out of curiosity?
 
I have an Asus motherboard that does synchronize all cores to turbo to the highest official turbo bin of the CPU if I set the memory to XMP. What I meant was will I be able to synchronize all cores to turbo to the 4930k's highest turbo speed of 3.9GHz without overheating or stability issues? Non of my cores run at a different speed.
 
I'm not talking about asynchronous clocking. I'm talking about core loads, for example CPU speed when all cores are running at full load or CPU speed when only 1 core is loaded and the other cores are in a sleep state.

It all depends on your motherboard. You can definitely have different per core turbo speeds, but most do not do this. Most motherboard sync the turbo speeds to be the same on all cores, AFAIK.

AFAIK only Qualcomn does as you say with the exception of P1. MB makers can use max tubro bin as their default bin for all cores, for example my 2500k always runs at 3.7GHz regardless how many cores it uses. This topic has been covered hundreds time already.

Look, all of my asus motherboards have a per core turbo setting. So don't link me anything - if your motherboard supports it, YOU CAN RUN different per core turbo settings. My motherboard does just that if I want to.

Go with the haswell setup. gl
 
I only would replace an i7 ivy-e with haswell-e, with you are losing quad channel,better cpu upgrades,more pcie lanes,unlocked multiplier,in one word downgrade
