I recently bought the 1080ti to my current rig and have after this purchase received heavy bottlenecking on CPU heavy games such as CS:GO. (on my 6600K).

I have tried multiple "fixes" and have even reinstalled windows to try and solve this, so I'm coming to that point where I think upgrading CPU might be a good answer.

What would you advice me to buy if I want to stream and still maintain a 300+ FPS ingame? I could perhaps add that I run a decent 160 FPS on average and it can dip to 60 and up till 230~ in certain areas.

Right now the 8600K is the cheapest choice but I heard that i7 handles streaming better, anyone who can confirm this?

I'll check this thread regularly so hit me up anytime. :)

if you need that fps while streaming, 8700k is the way to go thanks to its 6 cores/12 threads. If only gaming, 8600k is enough but only 6 threads will lose more frames than 8700k. Only culprit is, you will need new Z370 MB to run 8700k.

CS:GO doesn't use a whole lot of threads, so going from a 4C/4T i5-8600K to a 6C/6T i5-8600K isn't going to have much of an effect on that side. And the slight increase in clock speeds probably won't do much to improve it. And you're talking about having to get a brand-new motherboard (Coffee Lake CPUs aren't compatible with Skylake motherboards, & vice versa).

If you think you really need more threads, you could always look into getting a Skylake i7-6700K (or Kaby Lake i7-7700K, assuming your motherboard is compatible & has had the applicable BIOS upgrade applied). They're both running about $327 USD right now (https://pcpartpicker.com/products/cpu/#s=13&f=75,57&sort=price&page=1), which is probably about the same price as replacing your system with an i5-8600K & Z370 motherboard, plus you won't have to reinstall Windows. That would give you a 4C/8T CPU.

Another option, if you're really worried about having enough threads for simultaneous gaming & streaming, there's always the Ryzen option. It would be cheaper -- $263 USD for an R5 1600 & MSI Tomahawk B350 board (https://pcpartpicker.com/list/hht9pb), or you could even go to $355 for the R5 1700 (https://pcpartpicker.com/list/8TQ4jc) -- & give you a 6C/12T CPU (8C/16T with the R7), but you'd have to reinstall Windows.

What is your minimum fps in CS:GO when not streaming? CS:GO is not a cpu heavy title. I suspect it's your background streaming task causing your performance dips.

I am not sure why you'd want to maintain 300+fps. Now I am not going to go down the road of the eye can't see more than 60fps BS so it's all a waste but if your gpu is pushing way more frames than your monitor can display that is a waste.

I would have to agree with everything that ^vapour recommends. Go 8700k if streaming is your thing.

I don't know if this will be set as the solution, but to answer your question the information above is all from when NOT streaming, it is incredibly low for some reason, yet I have not really found someone I could compare my rig with. So I had to conclude that it was bottlenecking, it sounds like that might not be the correct thought though?

You could try running MSI Afterburner to monitor/graph all the important stuff like GPU usage, frequencies, CPU core usage, Memory usage, temps, pagefile etc etc to see what's getting maxxed when you hit those fps dips. That's what I use to see where I might need to make adjustments.

Did this already, nothing is out of the ordinary. I ordered 8600K now with a combatible motherboard, hopefully everything goes smooth and such. Anything in particular I need to do when plobbing the new parts in? I don't have a cdrom reader etc. should I just plob everything together though?

Will update you on the framerates and etc. and make a detailed solution.

The 8600k is a very nice gaming chip. Would like to know how it handles streaming at the same time.

I am not sure how much you know about building PCs but I'd take a little more care than just 'plobbing' the parts in. Just replacing the motherboard and cpu would still require a reinstall of Windows so it recognises your changed hardware properly.

What ram do you have currently? DDR3 or DDR4? The 8th gen Intel boards require DDR4 and would be able to utilise faster memory than the 6th gen chips. If you already have DDR4 you might want to consider faster memory in the future but wait until they are better priced.

Got DDR4 when I upgraded last time, I found somewhat of a tutorial online and will probably do a clean reinstallment on my SSD instead as it has been running on my oldest harddrive for century now.

I am just sad about losing all the data, any way to keep my data on my old harddrive or could I just unplug it and then install windows on my recently formatted SSD, then plug it back in?

Yes you can and it's probably the best thing to do any way.
Just to be clear.
Install windows to your SSD with your HDD unplugged then after all the rebooting etc and Windows is installed then plug in your HDD. You may have to make sure you are booting from your SSD as the BIOS may pick up the new drive and add it to its list as the first boot option.

I actually changed my mind, after further research I realised that I only need to buy the 7700K. My z170 board is combatible with the 7700K if I update BIOS and I did that a few weeks ago when I tried to reach higher FPS.

When changing just the CPU I don't need to really do anything except placing it slowly and applying the amount of cooling paste required right?

I saw some benchmark testing and it seems like 7700K do just as good as 8600K, so why not save 200 bucks. :)

Also since you were interested in FPS on the 8600K and 1080TI my friend has this setup and run 290 stable on Mirage whilst streaming. Hopefully this was a little useful.

That's good to know, thanks. Now you'll have to let us know how your 7700k handles gaming/streaming

Wrong: 8700k outperforms 8600k up to ~200fps on CS:GO (https://youtu.be/agcwU1ImIqE?t=390). However, choosing 8350, 8400 or 8600k doesn't make that much gap. Paying $120 extra for 200fps is worth every penny on a competitive level. Action, smoke, fps = better recoil.
