Hello. I plan on upgrading my CPU and I was thinking about buying an Intel Core i7 4930K (+ an Asus Sabertooth x79 mobo)

I would like to ask you if the performance will increase a lot after the upgrade?

I will give you an example:
I like gaming and that's what I use my PC for. One of the games I play is World of Warcraft. I raid heroic 25 man instances and I want to keep everything on Ultra quality (I'm ok if the view distance is lower though). The game isn't smooth at all, my FPS drops a lot and I am not able to stream the game at all which I would really like to do (I tried multiple settings in OBS). My graphics card is eVGA GTX 780 (running with settings for max performance).

I would really like to know if the new processor is gonna boost the performance a lot?

Thanks in advance.

I would upgrade to the 4770 or 4670 depending on what your old processor was.
We need to know in order to tell if the upgrade would be a good choice

EDIT: just saw where you put your previous processor I wasn't paying attention. and in that case the 4770 would be good but your real problem is WoW isn't particularly well optimized.

As far as 25 mans are concerned you will not notice much difference cause WOW is poorly designed. 780 is a really good card but in 25 man on Ultra setting performance will suffer no matter what parts you choose.

I suggest tone down settings a bit. You have to sacrifice on quality.

Hope this helps.

I wrote in the topic what is my current CPU.

Ya I just saw that and edited my previous post.

Do some experiments to see how sensitive your games are to core speeds and to the number of cores.

1. Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
This will simulate what a lack of cpu power will do.


Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
set to 70% and see how you do.

If this makes a big difference, then core speed is the issue.
A overclocked haswell is currently the best remedy for core speed.

2. See what happens if you disable hyperthreading in the bios. This might determine if a i5 or i7 makes any difference.

3. See what happens if you run on only 3 cores. This will give you some indication if moving to a 6 core cpu will be helpful.

Lastly, as good as the GTX780 is, test for the possibility that your card may be holding you back.

Run your games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.

The "best" CPU depends on your use situation

The 4930k and 4770k have basically the same cores, but the 4930k has more of them.

That means the only thing to compare is your processor's single-core performance to these processors because WoW is definitely not going to use all of the cores on either processors you're considering.

Here are those comparisons

Intel Core i7 4930K vs 2600K

Intel Core i7 4770K vs 2600K

There's no need to compare them to one another, since the 4930k will obviously be faster in applications that can use all 6 cores or twelve threads. But in case you're curious, here is that comparison anyway.


Intel Core i7 4930K vs 4770K

But the question really is

Do you an upgrade to either in the first place?

To test, run everything you plan to run in an ideal situation (e.g. the game, the streamer, your music, whatever). Then open up a CPU and GPU usage monitor (try this link for how to use the monitor built into Windows). While that is running, conjure up your worst case scenario in the game while everything else is running.

Close everything and analyze your data. If your CPU had any maxed cores, you need faster cores. Count how many cores were maxed. You don't need to buy more than that. Also, look at your GPU usage. If it's not maxed out, you GPU is fine (I suspect that's the case with a 780). If it's maxed out, then graphics is the issue.

You're right that they have different names, but I still stand by my previous post. I was talking in terms of performance, and perhaps I should have been clearer.

To clarify, look at the benchmarks. They are core-for-core, clock-for-clock similar enough to where there's likely no perceptible difference of importance. Even if there's enough difference to notice something in a side-by-side comparison (unlikely), it's certainly not anything that should turn a buying decision one way or the other. The 4770k wins such a small margin that I would recommend not considering it as anything of importance. But thanks for clarifying my terms. The cores are Ivy and Haswell -- correct.

Holy sticks! I was doing research for another issue, and I found a solution to this. It seems that WoW greatly improves on a powerful processor with many cores compared to others. Take a look at the linked quotes below showing a significant improvement from more-core processor upgrades.

WoW does enjoy the 3960X's larger cache, here we see a 13% increase in performance compared to the regular Sandy Bridge parts.

Also, here's confirmation from Tom's Hardware review of the 3960x.

Ironically, the most mainstream game in this comparison is the one best able to take advantage of Intel’s new $1000 processor. World of Warcraft doesn’t fully tax our GeForce GTX 580 graphics card, so swapping CPUs in and out does impact performance quantifiably.

Also about the 3930k.

Perhaps the most processor-bound game in our suite, World of Warcraft has little trouble taking advantage of overclocked Sandy Bridge-based cores at 1680x1050 and 1920x1080. Of course, cranking up anti-aliasing shifts the game’s emphasis back onto graphics.

I don't really know WoW very well, but it seems like there are several versions of the game, and I am not sure whether they tested the same version you have. But as long as your version is not older than the one they tested, the same should apply; namely that better processors help its performance a lot.

Having more active things on screen to track has created primarily CPU-driven tasks in every game I've played, though the GPU does have to work as well. In games without good optimization, you might be limited to the speed of the cores it accesses, which might be fewer than your processor has. If that happens, overclocking is the only remedy. That has its limits, though. WoW's been around a while. If I had to bet on it, I'd put money on the game being unable to fully utilize modern processors - $5. Anyone?

Yeah, taking advantage of more would require rewriting a large portion of the game. Since stability is a major concern with MMOs, they probably aren't going to do that until the next Warcraft game. But - hey - who knows?

Looks like your right since the recommended are old dual cores(core 2 and athlon X2) and old Graphics card(8800 GTS) with windows 8. It was updated 3/4/2014
