8600k or 8700k for recording gameplay?

[cloakshire]

Firstly, thank you for taking the time to read this. Hopefully I'm posting this in the correct section and if not, perhaps a mod can move it, but I'll get to the point. I'm currently looking to build a new system capable of recording gameplay at 1080p/60fps. I'm not looking to stream, but rather locally record to my hard drive. I'm unsure if the 8600k will be enough for my specific needs or should I step up to the 8700k?

My Current system:
Processor: AMD FX-8150 8-Core CPU (3.6Ghz) (OC'd to 4.1Ghz on stock cooler.)
Motherboard: Gigabyte GA-970A-UD3
RAM: 16gb G-Skill Ripjaw X Series
GPU: AMD Radeon 6950 2GB
Boot Drive: SanDisk 120Gig SSD
Storage Drive: Seagate 1TB 7,200 RPM HDD
PSU: CoolerMaster 850W Bronze
OS: Windows 7 64-bit Home Edition

I don't particularly play demanding games like Crysis or the new Battlefield. I tend to play less intensive games like Vindictus, Runes of Magic, Planetside 2, Dark Souls, and possibly Intrepid Studio's new title Ashes of Creation.

My current system is able to handle most of the games I play with a framerate around the 40's to 50's. However, during times of high action, motion, or when there are many entities on screen, my frame rate stutters a lot, especially when recording. Here's and example from my machine. As you can see in my fps is not consistent & greatly fluctuates. Here's an example of what I'm hoping to achieve. Notice how much smoother the gameplay is despite there being more going on than in my video.

So, will the following build be enough to net me smooth gameplay at 60fps when recording? Or will I have to swap out the 8600k for the 8700k? With this new system, I'll most likely be transitioning from using OBS to Nvidia's Shadowplay when recording due to its lower impact on cpu performance. This build totals just under $1,500 and if possible, I'd like to keep it that way. This means that if I end up needing the 8700k, something in the build has to be compromised to stay under budget.

New system:
Processor: Intel i5 8600k (Turbo Boost Disabled & all cores set to 4.2 Ghz)
CPU Cooler: CRYORIG H7
Motherboard: ASRock Z370 Extreme4
RAM: CORSAIR Vengeance LPX 2400Mhz 16gb 2x8
GPU: EVGA GTX 1060 FTW2 6Gb
Boot/Storage Drive: Samsung 850 Evo 500Gb SSD
PSU: EVGA SuperNOVA 850
Case: DIYPC Vanguard-RGB
OS: Windows 10 64-bit Home Edition

I know this post was fairly long and whoever has taken the time to read this has my sincerest apologies for the length, but my gratitude for taking the time to read it. I look forward to any kind of constructive advice that will help me with this endeavor. Also, just to note, I am well aware that Ryzen is an option, but after having two AMD machines so far, I really want to try Intel for the first time.

12 threads vs 6 threads, For recording I would go with the 8700k for sure.

You don't need 850W. 550W is more than enough for 8700K and GTX1060. If you think upgrade to 1080Ti in the future, then get 650W.

There's no doubt that a 12 thread CPU would be better when it comes to recording gameplay. Not only that, but it would cut rendering times down when I go back to work with the videos. However, is the 8700k really needed for my particular situation? There's two reasons why I remain uncertain on which one I should get, and they are as follows:

1. From what I've observed, before Coffee Lake came out the 7700K was the go to chip for gaming/recording. Couple this with the fact that in quite a number of benchmarks, the 8600k is beating the 7700k in both single and multi-threaded performance despite having two less threads. (I'm aware that the 6800k was also a popular choice, but in terms of price, the 7700k was the better overall value in my opinion.)

2. Based off of the performance I have on my current system vs the performance gains I should see with my new build, an 8600k/gtx 1060 "should," be enough. I say should in quotes because this is pure speculation that I'm not 100% sure of.

In short, yes the 8700k is going to perform better, but it seems like overkill. If it's needed, then I'll get it, but if an 8600k can still do the job, I'd rather save the money. So, will the 8600k be enough or do I "need" the 8700k? Granted, if my thoughts about the power supply are wrong, this will allow me to put more money into the processor and go with the 8700k.

Please correct me if I'm wrong here, but isn't it good to get a power supply that's well over what you need? Not only does this keep an upgrade path open, but the PSU should last longer. For example, say I have a system that requires 500W. I could get a 550W power supply, but then it would be running at 90% during peak power draw. Stepping up to the 850W would create a situation where the psu is only being pushed to 58%. It would make sense that since the 550W is being pushed near its maximum, it would degrade faster than the 850W.

Again, I could be misinformed, so please do correct me if need be. If I'm wrong about this, I'll gladly step down from an 850W to a 600W. The money this saves me can go towards the 8700k.

If you search internet, you will find TDP power usage: i7 8600K and 8700K TDP is 95W, GTX1060 is TDP is 140W. GTX1080Ti TDP is 250W. You can add additional power for overclock, fans, hdd and other accessory for max 150W. I have seen in this forum that the recommendation is 650W for someone with i7 8700K and GTX1080Ti. Of course this is high quality power supply.

Again, please correct me if I'm wrong, but isn't using a processor's TDP to measure power usage inaccurate? From what I've researched, Thermal Design Power(TDP) is all about measuring a processor's thermal generation so it can be paired with an appropriate cooling solution hence why coolers have a max TDP rating. It's a common misconception, but you can't just say that the 8600K & 8700K are going to draw 95W becasue of their listed TDP. A stock 8700K can draw up to around 140W of power under full load. If overclocked to 5.1Ghz, it can draw up to 220W which is well beyond the assumed 95W.

I agree that a 600W or 650W power supply will be more than enough for me, but can you please answer my initial question regarding the use of larger power supplies?
