Does CPU overclock affect GTX 970?

Hello, i made a topic like this yesterday, but i think i formed it a bit wrong. I have a 970 and an i5 4460, my 4460 does bottleneck my gpu in the CPU intensive games, like GTA V and Battlefield 4 (could be optimization problem in BF4). So, i've watched alot of videos where increasing the cpu voltage gives them like 10 fps more in cpu intensive games, but in the videos they use titans n' shit. So my question is, if i get an i5 6600k and overclock it to around 4.8ghz, will there be a good difference from i5 6600 (non k), if you didn't catch it, i have a gtx 970.

Thanks for all replies!

  1. An overclocked i5 6600K will beat a regular i5 6600
  2. The 4460 shouldn't bottleneck a 970.

    Yes, i do understand that. But will i see a good difference, or should i say, will my gpu be able to utilize the power provided by the cpu overclocking?
  4. yes, IF the 4460 is actually the bottleneck which it almost certainly is not, gta V and BF4 at 1080p require more than just a gtx 970 to fully run the game smoothly at max settings, then you will see a performance bump by upgrading the CPU.

    however, like people probably have been telling you... the CPU is most likely not bottlenecking your card. Chances are you are expecting more out of your card than it has. the gtx 970 is a great card, but it will not max out games at 1080 once you start throwing in eye candy

    also, no, if you overclock the CPU it wont affect the gpu at all (99% sure of this)

    A 4460 won't bottleneck a 970; or at least it shouln't. Getting a 6600K to 4.8 GHz sure makes a difference, but i don't think that the issue is there. I think you are trying to squeeze more from that GTX970 than it's able to give.

    A game's CPU and GPU needs are largely independent of each other. Your framerate will be limited (at any particular moment) to the lower FPS number that either your CPU and GPU are able to deliver.

    Example: In one scene, there's a pan of a landscape, with a lot of detail. CPU needs are low, GPU needs are high. Your CPU can deliver 200+ fps, but your GPU can only deliver 40fps at highest graphical settings. You'll get 40fps.

    In another scene, there's an explosion, with a lot of CPU-heavy physics. Your GPU can deliver 60fps, but your CPU temporarily can only deliver 35fps. In this scene, you'd get 35fps.

    ~

    In the GPU heavy scene, you have the option of turning down details or resolution to get more fps. In the CPU heavy scene, most games don't have any settings you can change that will reduce CPU load, so you're stuck with what you have.

    Yes, ive been thinking this to myself aswell. But when i monitor games and my gpu usage is at like 50-80% usage it makes me think something is wrong / my cpu is bottlenecking. For games like the witcher 3 i am super happy with my card, i get 60 fps maxed out (hairworks off, range visibility on high) almost everywhere, except big cities. And also in big cities my cpu usage sometimes reaches 95-100%. Here is some monitoring from GTA; https://gyazo.com/f435d7ba54fd5f25171c8622db7a7e44
    https://gyazo.com/bda858c9dc5072b34734006ab3501cdf

    My CPU usage is at like 97% while my gpu usage is at 70% is it really supposed to be like this?

    Okay, thanks for a detailed explanation and not a "4460 doesnt bottleneck 970." :)
  9. ^ Less than 100% GPU utilization, while the CPU is at 100%, suggests your CPU is what's preventing your framerate from being higher when you're seeing that.

    Yes, thats what ive been thinking aswell. Also, if id buy a new cpu would you suggest i5 6600 or the "K" version? My problem is that i need a new motherboard and new ddr4 ram if im getting the K version, and i dont know if the struggle is worth it for the overclock :/. (id save 100 dollars if i im going with the non K version)
  11. I'd probably stick with Haswell, since you already have a board. An i5 4690 or 4690K would be about 15% faster, due to higher clockspeed. An i7 4790 (non-K) is clocked ~17.5% higher and has some extra cache and hyperthreading, which may or may not help in these games, and a 4790K is clocked about 30% higher than your current CPU.

    Right now, a 4790K is basically the fastest CPU you can buy, and even with 30% more power, you can imagine that there will still be times in which your CPU is the limit. It's just a matter of buying enough CPU that you're happy with the framerates you get.

    Thing is, my motherboard is not a Z97, so i cant overclock, and if im gonna get a new motherboard i might aswell get a H110 or Z170 and get the i5 6600/K, because the i5 4690K is basically the same price as the i5 6600/K. Also, digital foundry's test showed that the skylake processor has a quite good performance increase compared to haswell.
  13. It's up to you whether or not the cost of new RAM, motherboard, and a new Windows license is worth the improved performance of Skylake over Haswell.

    For what it's worth, a 4790K's stock clocks are nearly at what you'd likely get from a max overclock anyway. 4.4-4.5ghz is a pretty reasonable expectation with reasonable voltage, and it already turbos to 4.4 (1 core, 4.2 4cores) on a non-Z motherboard.

    So do you think the stock 6600 at 3.9 ghz boost will give me a fairly good difference aswell?

    Thats a good point, the 4790k clocks seems good to me (im not a cpu expert :d), and regarding the windows license, you can contact microsoft and tell them that you have bought new hardware, they'll fix the windows license for you.

    Edit: So are you sure that turbo works on a non Z motherboard?
  16. Yeah, it does. Should work fine!
  17. Anyways, when im at it, what about the i5 4690K, people say its almost just as good as the 4790K when it comes to gaming? I mean its like 120$ cheaper and if i want to overclock it i could just grab a new motherboard down the road.
