Hello.
Today I am running a i5 750 (not overclocked) and I am considering upgrading. I don't know how much of an increase I would notice in games, photo/video editing and 3D modelling etc.
I mostly play games but also do some photo/video editing and 3D modelling.

I put together a package that looks like this:
Asus Z97-A ATX
Intel Core i7 4790K 4GHz
Corsair 8GB CL9 1600Mhz VENGEANCE LP, I already have two of these so I'll be running 16GB (4x4GB)
Noctua NH-D15, NH-D14, or NH-U14S, not sure here so could need some tips. Today I am using Corsair H50 liquid cooler and while I have had no problems with it I decided to go with air cooling this time.
Last but not least I chose a Fractal Design Define R4. I have the older R2 version today but with all the changes they have made to the R4 plus USB 3.0 I feel that it would be better with a new case.

I also put a X99 build together but with the DDR4 and everything else it was simply too expensive. It almost ended up double the price of the package above.
This was with an Asus Motherboard 5820K and 8GB DDR4 and the same case and cooler.

So the question is, would it be worth going from a i5 750 to a i7 4790K? Would it be worth the price for the performance increase I would get?
Will the 4790K be future proof?

As I'have understood it the 4790K is better/the same in games compared to the 5820K. But I assume this could change if games start to use more cores.
So anyway the 5820K is out of question because of the high price.

So basically I have two options, wait until I can get a 5820K or something similar with DDR4 when the prices have gone down to about the same as Z97 4790K and DDR3. And stick with my i5 750. And as I mentioned I don't know what kind of increase I would notice in games and in general with a 4790K over my i5 750.
Or buy the 4790K and another 8GB ram now.

Also worth mentioning is that I have purchased a GTX 980 that I will recieve next week, I don't know if my i5 750 would be a bottleneck to this card?
And I already have two SSDs and a Corsair AX860 PSU.

What would you say is the best choice? Thank you in advance!

The PhysX is from NVIDIA, but it mostly require the CPU to make the numerical analysis of a thousand equations to make the games look more real. That means your CPU is really holding back your system. Be careful to not overheat the processor (+70C).

I think you already know this site, but it is worth to take a look:
i5 750: http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5+750+%40+2.67GHz&id=772
i7 4790k: http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-4790K+%40+4.00GHz&id=2275
i7 5820k: http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-5820K+%40+3.30GHz&id=2340

By changing the processor you will have 3x~4x the power...

Upgrade to DDR4 is not worth by now; it is (always) expected that the prices will drop in six monther (at least 20% difference). And you won't notice a big difference; you could notice if upgrading from 1600 to 2600mhz bandwidth, for example. The new memory RAM (DDR4) has a lower power usage, but the 5820K has a higher power energy usage, so it is balanced.

I think it still will take some time to games use all cores, because they only use it to render textures, polygons and modeling. The GPU is responsible to fill the surrodings with effects and texture, so it is somekind more important. The 4790K, +8GB RAM and Z97 motherboard is the best pick, in my opinion.

Thank you. But do you think i'll notice a big improvement in games and just in general when doing CPU heavy tasks going from i5 750 to 4790K?
It is not overclocked and I don't think I will ever do it. I gave it a try a year ago but it didn't go very well, and when trying to reset it to default clocks I had to reinstall Windows because BIOS also reset AHCI to IDE amongst other things.
I'm sure I could do it better if I read up on it more but I don't know..

Yes, you will notice a huge difference actually, because since the first generation of Core i family, Intel developed a lot of new features, like Turbo Boost, Hyper Threading, lower power usage and larger memory bandwidth (wich means 'faster' for short).
You don't need to overclock. People abuse of thiw word; mostly of the time we are just web surfing, listening to music and watching videos, and if a Celeron/Pentium (low-end processors) cand easily handle it, why would you need and overclocked CPU to do the same (even if they can handle the lastes games).
You've just bought a powerful video card, for real. It will be good for gaming for a long time (future proof) and the processor is also great for 3D-modeling and rendering (http://superuser.com/questions/790418/why-are-videos-rendered-by-the-cpu-instead-of-the-gpu).

There is always a few downsides to being early adopters for The bleeding edge tech. X99 platform can blow pretty much anything else away in terms of production and raw speed. The best thing about Haswell-E and even Ivy Bridge-E is that there is a true IHS and TIM by using traditional solder. ImPo. If you have the money and can put up with the wait for faster and more dense DDR4 Memory with a lower CAS and just get what they have now. Then go for it. I would. If your more of a performance per dollar person then Z97 is the way to go. either a i5 or i7 devil's canyon SKU. and a decent motherboard. I like the MSI Z97M Gaming M-ATX.

Thanks for the replies. After giving this more thought I'm actually considering staying with my i5 750 and I might try to overclock it. I certainly have a good cooler for it. I don't know anything about overclocking though so I will have to read guides, does anyone know of good guides for P55 i5 750?

I'm still not sure though, but I will wait until I have my GTX 980 in a couple of days and give it a try. If i notice that my CPU is a bottleneck in the games that I play I will most likely upgrade. But I should also try overclocking of course.
I should also mention that I play games at 1440P.

That is the way to go really. If your CPU does what you need and your not on, like i said before, "the bleeding edge" Lynnfields are still marginally faster than AMD Piledriver (FX, 43xx A-10 Richland quad core) overall. Still it is quite faster single-threaded. Like you said get a GPU now or soon then upgrade the rest as you go. Then you can enjoy the new graphics card regardless. Oh And the GTX 980....just don't look even look at the reviews just get one then go back to youtubeland and watch em all and be the envy of your fellow gamers.

I got my GTX 980 today and just installed it.
I ran a few benchmarks with my GTX 580 in Mafia 2 yesterday with different settings (PhysX off, Graphics high and low etc) and resolutions. And when I ran them today with my new card I get about a 100% fps boost with PhysX turned off. With PhysX turned on and set to High I get the same FPS as my GTX580 did. I didn't know Physx is so CPU Heavy. I've made sure PhysX is the to GPU in Nvidia control panel as well.

I also tested the flight sim DCS World which is supposed to pretty CPU heavy. And it sure is because I'm not even getting 1 more FPS with my new card. So that game really is held back by my CPU. I did try the Auto Overclock setting to 3.6GHz in BIOS since I don't know anything about overclocking and that gave me 10 more FPS in DCS.
So if I'm going to be able play DCS World with Oculus Rift I will have to upgrade. The question is 4790K or 5820K... I'll have to think about it.

By changing the processor you will have 3x~4x the power of your current processor. For sure this processor won't bottleneck your system for a long time. Both processors are future-proof. The price doesn't have much difference, so it is a good choise pick the 5820k. BUT, the new-released motherboards may be too expensive depending on what brand is your favorite. If the difference is too much (more than $150) I suggest you to pick the 4790k then, otherwise you will need +$200 for the new upgrade.

About the differences between the processors, it is easy to notice the new model has +2 physical cores, requires more power energy, have support to more memory RAM capacity and is faster, doesn't have a built-in GPU, and the maximum temperature tolerated is 66.8C compared to 72.72C of 4790k.

Good luck to choose. Hopefully I gave you usefull information.


Edit~
My bad, the Asus Z97-A ATX actually supports both CPU.
