i5 7600k or i7 7700k - is the extra worth it.

So im building myself a new pc, but hnsure about which chip to get. I can get the i5 7600k for £225 or the i7 7700k for £325.
Is the difference in price worth it for the improvement in vr?
More to the point, aside from the mild increase in clock speed which can most likely be matched via overclocking is there any benefit to having multi-threading?
On my current i7 950 ive always had it switched off and its been pretty flawless. But i think its time to upgrade. That said i have this chip overclocked at a rock solid 4.2 (its 3.07 as standard). According to oculus home it doesnt meet the minimum spec however and vr experience could be affected (utter horseshite).

So cmon guys what say you all?
£225 for an i5 or an extra 50% for the multi-threading. Bear in mind thos us purely a gaming rig, i do occasionally make images and videos but thats very much a second to vr gaming.
@cybereality im very much interested on your opinion on this. If anyone knows the technical difference as far as vr or future vr is concerned its you. So I'm counting your vote as 3 votes ;)

    You say your current CPU works absolutely fine - why upgrade at all?

    Also, what graphics card do you have - you say it's all about gaming, that's what matters once you have the CPU sorted.

    1070 ftw mate, so its not an issue.

    Im after the upgrade primarily for the motherboard and ram.

    I have 2 850 evo ssds in raid but its pointless as i dont get the correct speeds because it doesnt have sata3 (just a fake sata 6gbps which runs 2 channels via a single express lane and is a max of 5gbps so im not getting close to the correct speeds.
    Also my pcie is gen2 and although not saturated yet, its only a matter of time before it becomes an issue.

    Go for the i7 7700K.
    Great chip according to reports, little larger L2 cache, and as you mentioned multithreading. While current games may not take advantage of it , only a matter of time - and probably not too long, before new ones will.

    If I were building a new system today, it would be my choice.

    Edit: Btw, I upgraded from an I7 920 X58 system to this I7 4820K X-79 system a little over three years ago. While my cpu overclock was a modest gain as well, the platform and memory change gave me significant improvement in performance. I am sure you will be pleased with your upgrade.

    A 1070 and 850 evo SSDs - it'd be rude not to bring the rest up to scratch.

    I'm not sure there would be a huge difference in VR but the 7700K is the better chip and I think it's worthwhile to spend a little extra to get a chip that will last longer.

    I have the i7 7700K and it is a great chip, I have a stable overclock at 5000 GHz.  I am using the swiftech H 240 X2 all in one water cooler to cool the chip. A good air cooler can get a decent overclock around 4800GHz. I have the Asus z270e for the motherboard. 
    This video explains the differences in gaming. Paired with a fast memory the i7 7700K shows pretty decent increases vs the i5 7600K.

    thanks for the video @paesan the decision is pretty much made for me now
    7700k it is and 3200 vengance ram (3000mhz peasants lol)

    now the question i suppose is the board to take.
    i was looking at the asus stix z270H - linky
    it looks like th best all rounder.
    I'm not bothered about usb 3 incompatibilities as i have 2 inatech cards and will continue to use them, but can anyone suggest a decent comparable board?
    The aesthetics do come in to play though people as i dont want a fugly board (i currently have this x58 and my god it's nasty), but the strix does have the rgb LED's and the outputs to connect more for case decoration which coupled with my kb and mouse and my 1070 ftw would be a nice option

    as always guys, any input anyone has will be greatly recieved :)

    @elboffor, the differences between the Z270H and Z270E are not that big. The Z270H is a great board for the price. For my use the bluetooth and wireless are must haves, if you don't need bluetooth and wireless on your MB then this is a good choice. Onboard sound is slightly different, according to the specs the onboard sound in the Z270E is superior to the Z270H.  As you stated no rgb LED lighting on the Z270H. I like to make my case look good so the rgb LED's  was another feature I was looking for.

    On a side note this question is for cybereality. A nice feature on many tech forums is the ability to add the PC system specs to the user profile. This would make it so much easier to assist others when problems arise. Can this feature be added to the forum. Thanks.

    TL;DR: If you are only planning to game on it, the 7600K would be your choice. Put the money you save from purchasing the i5 towards a better GPU. 

    In the latest AAA "2D" games, a 7600K will rarely be a bottleneck, especially when playing in higher resolutions. In a VR workload, you are more likely to be bottlenecked by your graphics card with the 7600K. 

    I'm running the 7700K right now, but I use my PC for more than just gaming. The difference would not be substantial in gaming environment, unless the workloads are well optimized for more threads. There are some games that will take advantage of the i7, but many won't (as well as they could).

    On the other end, the extra performance of the 7700K will let it remain more relevant as time goes by. If you have other uses for the PC that would benefit from more threads, then the extra money for the 7700K would be worth it.  It can be hard to say what's "worth it," as it really depends on your budget and how long you typically wait between platform upgrades.

    I went form the i5 to a i7 and the pc is noticeably faster, but aside from that I'm not sure it makes a real difference to gaming. I will say that going to an i7, 8gb ram, and gtx 1080 got rid of the annoying 'your pc does not meet minimum' message, which is a big plus, I hated that.

    I think an upgrade from a i7 950 to one of those will bring massive improvements. I've got a Skylake 6700K and saw enough improvements. Just watch this YouTube video to get an idea what a CPU can do even when they are all Overclocked the same.

    Manu thanks for your replies everyone :)
    (except cyber who tried to derail my thread with his off topic spam, I'd never do that).

    The price point and current gen argument is definitely one worth making. But cost is really a concern, value is more of it. This is what i was strugling with and is the reason i held on to my current cpu as long as I have.

    After seing as the first video posted shows the difference in performance of both chips equally clocked and using the same gfx card (a gtx 980 ti which is slower than my 1070 ftw) i think that coupled with the argument of longevity has made my mind up.

    I'm still open to input on the mobo though.

    I was forced into an upgrade a few weeks ago, ended up getting the i5-7600K and GTX1070, replacing the i5-4690k & GTX 980Ti OC. Would really have liked the i7-7700K and 1080... The difference allowed my to keep my order for the Nintendo Switch.

    I was quite surprised when I saw the Digital Foundry review between the 7600k and 7700k. Normally HT doesn't do much in games, but there were a number of titles that gaining substantial FPS with the 7700k over the 7600k with the same 4.8GHz overclock.

    I just upgraded from an i5 6500 to an i7 7700K and tested it in Lone Echo. I didn't notice anything better in VR and I say save your money and upgrade your video cards instead.

    Necroe'd thread but still relevant. I swapped my old I5-4690 (4 core, 4 thread) to an R5 1600x (6 core, 12 thread) about a month ago (before getting OR) and the difference was pronounced. But there is a caveat to that, there is no difference in an ideal situation for the vast majority of games (ie benchmarking). The reason is very few will take advantage of more than 4 threads/cores. Some do though, like Fallout 4, Hitman, Doom and a few other big names.

    The real advantage is in the non-ideal, every day situation. Windows 10 will install updates, run security scans and so on whenever it feels like it. There is absolutely no way to disable this for more than a brief period. You may also want to download or install a new game while playing another (please make this an option here like on steam, my system can take it). My old I5-4690 would choke under such load. It could download a game or play a game, but it couldn't do both without serious performance loss since those 4 threads had to be shared between different things. With the greater core/thread count of an I7 or R5/R7, that just isn't an issue. No sharing is needed and thus no performance is lost.

    The above is particularly relevant in VR. Between OH, SteamVR and the game itself, there's a lot going on. Oculus in particular is really bad about going 100% in a single thread all the time.

    Short version: clean system benchmarking shows no difference in most games but real world performance can be dramatically different.

    I got the 7700k anyways. Brilliant chip.
    Not even overclocled it yet but its good to knpe in the future i will have the headroom to do it.
    By comparison to my old qx950 i saw an immediate tracking improvement and not once have i had any issues.
    I run the fully bloated win 10 with mcafee and everything is set to update and scan do whatever it likes amd it never skips a beat.

    I've got a 2600K (@4.8ghz) and have been a loyal Intel customer for many years - hell, I even own a decent chunk of stock. But in the hope that developers will start to utilize more threads in their games, I'm not buying another 4 core chip, and their 6/8 core chips cannot remotely match Ryzen from a prize/performance viewpoint.

    I've decided to wait and see if Intel makes a move - e.g. slash the current prices and sell Coffee Lake at a competitive price. I hope the 8700K is gonna be a winner with proper TIM and overclocking potential.

    Otherwise I'm jumping ship for the first time in decades!

    There are a few minor differences like:

    • Hyperthreading: All i5 processors are Quad Core and hence have 4 physical cores serving 4 threads. All i7 processors also are Quad Core but they are equipped with Hyperthreading technology which enables each core to serve 2 threads, hence the OS sees it as an Octa Core Processor rather than a Quad Core Processor.
    • Cache Size: RAM minimizes the use of Hard Drive similarly Cache minimizes the use of RAM. The more the Cache size, the more data can be accessed quickly. Most i5 processors(if not all) have a cache size of around 4MB (3,4,5 or even 6MB in some of them) but almost all i7 Processors have 8MB cache, which is significantly more, thereby allowing more amount of data to be accessed quickly.

    No one considering the i5 8400? great little 6 core chip. I have seen a significant boost from it and it performs very close to the 17 7600 chips in benchmarks. Seems to be the best value for price at the moment.. does need a new board but in my case coming from a 2500k it was a no brainer

    Well, if you think about it, it´s really not that much of a surprise.
     AMD Finally had something to throw back at Intel, so offcourse they had to lower their prices if they still wanted to be part of the market share.
