Can my i7 4790s still stay in rig, or is it time for it to go?

Just as title says. People say all the time that unless you have an i3 or lower, it won't bottleneck the system. Thing is, multiple sources say otherwise. A you-tuber by the name of "The good old gamer", has stated that even the titan x pascal style, bottlenecks the almighty i7-6700k clocked at 4.5 ghz at 1080p. Obviously, at higher resolutions, it doesn't bottleneck the card as it renders less frames since it's more demanding, making the gpu the bottleneck rather than the cpu.

Which brings me to my next question. I have the 1070 FTW and will plan to overclock the card. I game at 1440p 144hz, and will eventually shoot for the 144fps in all games when I get the chance to sli. I may even overclock my monitor to get even higher hz, with 2 1070's oc'd. With this in mind, I think my i7 4790s will bottleneck my gpu sli config. plan that I have in the future, as even now with one card, I play batman arkham knight and am seeing 90% utilization. Granted, 10% bottleneck isn't much, but when I go sli, that will grow to 50-60% utilization. Now, I only tested this one game, and it could potentially be the 90fps lock on the game, and not the cpu.

So in conclusion, should I upgrade to an i5-6600k, an i7-6700k, keep my cpu, or wait for kaby lake/zen? Which path should I take, as I am new to pc gaming, and I wish I didn't buy a pre-built system so that I would've chosen a different cpu. Now that I have more knowlege of pc's however, next time I will build my own system and will chose something better than the s version. Finally, I know that the s version can't be overclocked, but can I overclock it to it's boost clock,making the boost clock, it's base clock, while disabling turbo boost? Thanks for the help in advance.

System info:
gpu: 1070(maybe sli later?)
cpu:i7 4790s
mobo: M51AD (by asus)
ram: ddr3 @1600mhz
monitor: dell s2716dg (g-sync, 1440p 144hz, 1ms)

  1. Okay, Well that "The good old gamer" person is full of sh**. The i7 6700k at stock would not bottleneck the Titan x my i7 4790k won't bottleneck the Titan X either. The i7 4790 will work perfectly fine with your GTX 1070 and even if you go for a SLI it will still work without any issues or bottleneck. You will see maybe a 5-8fps difference in games with the i7 6700k but I would wait until Intel releases some more CPU's then upgrade your motherboard and CPU.

    I appreciate the quick response, and helpful info. Two questions. One, when you said 5-8 fps difference, were you talking sli, or single 1070? Second, do you think I can at least overclock the i7-4790s base clock (3.2 ghz), up to it's boost clock (4.0 ghz) and then disable turbo boost? By logic, I think yes, because it overclocks it to 4 ghz automatically with turbo boost, so it should manually do it as well.

    I was talking about the CPU difference in 5-8fps but not all games take advantage of SLI yet but in the future I see it taking advantage of it. The Intel core i7 4790 is a locked CPU meaning that it can not overclock. Boostclock is not the same as a real Overclock. Boostclock doesn't stay at what its boosted at 24/7 it only activates when games are launched and etc. Honestly boost clocking might make a tiny difference but as I and many other experts would say (I am quite advanced in computers but not a so called "Expert." But Overclocks by a few GHZ is not going to affect performance, maybe 3-4fps boost? It really doesn't see an affect unless you are OCing an Unlocked CPU with custom watercooling and OC it to like 4.8GHz and etc is when you notice a difference. By all means go for a SLI 1070's it will be great, Also if you turbo boost you can not disable turbo boost and stay at the turbo boosted GHZ. So lets say you were to Turboboost to 4GHZ, If you ever were to turn off turbo boost it would go back to its normal 3.4GHz I believe is what the i7 4790 is.
  4. Hey sorry that I took so long to reply. Been busy lately, and totally forgot about tom's hardware with all that's been going on in my life. Anyways, back on topic, I know when you said 5-8 fps you meant cpu. The reason why I asked whether it was in sli or not for the 5-8 fps is that the cpu gets more stressed when it has to load more fps. Thus, sli would stress the cpu more than single. That was why I was asking whether or not the 5-8 fps from cpu would be in sli or single. I know of course that sli provides much more than a meager 5-8 fps. Sorry for not clarifying that.

    Now, I know that disabling turbo boost will not enable me to get boosted speeds. What I was asking was if I can disable turbo boost and manually oc it up to the boosted speed. For example: the i7 4790s base is 3.2 ghz, and boost is 4ghz. I know that since it's not K, I can't go above 4, but can I at least set my base clock to 4ghz manually while having turbo boost off? That way, it stays at 4 ghz and doesn't change dynamically. Thanks again.

    Keep the i7 4790s, it's a good match for a gtx 1070 and even SLI. I run an i7 4790 with a gtx 1070 myself and my i7 has no issues powering it :)
  6. Ok. Thanks for the clarification. I was about to go for kaby lake/zen cpu. But it seems others are saying I am just fine. Thanks for the replies guys. By the way, is the i7 4790s similar in performance to i7 4790?
  7. yes it's similar, it's a bit lower clocked, but also has the 4ghz turbo boost, so there is probably not any noticable difference :)
  8. the ''s '' is a low power chip in that series [65w]

    http://ark.intel.com/compare/80806,80807,80808

    now how that translates from the 85w 4790's ?? the clocks [boost] look good and close to the same

    funny how its not listed as a devels caynon refresh as the 4790k is ??

    i dont see where your hurting useing it i would
  9. It's not that I am hurting using it now with single 1070, it's just that I thought 1070 sli would be too many frames for the cpu to render, causing the utilization of gpu to lower. Now I know though that I am good to go. So would you guys say that it's not worth manually oc the cpu up to 4 ghz as it's base, while disabling turbo boost? Or should I oc it?
  10. I would think its a good match I'd have no issue with a 1070 and this i5 4670 - it does well with this 980ti

    I think your in good shape and having a 17 with the multi threading makes it a bit better I see no reason to upgrade unless you just want to do so for the heck of it

  11. So I am guessing by your answer that it's not worth the hassle to oc up to it's boost either right? Just let turbo boost dynamically change the frequency for me, since I already have a strong enough cpu correct?
  12. Correct :)
  13. Alright. Thanks guys. :)
  14. the ''s'' and non ''K'' chips is locked you need a ''k'' to overclock [4790 ''K'' ]

    looks like you got your best answer so good luck and enjoy
  15. I know. But that's after 4 ghz, I am talking about making the base clock it's boost clock (4ghz) which turbo boosting technically does on it's own. So that is possible. But like he said, it's not worth the hassle when turbo boost will automatically oc it for me.
