If you really are wanting to go full retard I'd go with a volt modded Titan a ask 8 pack for a 5.4Ghz 6700/7700k all wrapped up in the best water loop. That's the only way to cut above anyone else and garrenteed 144Hz+ gaming for a while. Just don't try and stream at the same time.

Actually switched from 6700K @ 4.9Ghz to 6800K @ 4Ghz because I want to play games, while streaming radio and using TS

The fps is better, everything smoother and doesn't "semi crash" the system every time using alt+tab.....

I was going to buy the 8700K but then saw the 2560x1440 reviews with GTX1080ti, and compared the same games with the 6800K @ 4Ghz and 1080ti I have, ain't going to bother.
At best the difference is 1fps!!!!!!!!!!!

So yes I am GPU limited, oo poor shame on me, a 2Ghz clocked GTX1080ti is bottlenecking me.

Well you're probably draw call limited.

I couldn't call it "draw call limited" when the difference is 1fps......Hell I can raise the fan speed on the GPU and gain that 1fps easily. But enjoying having the system quiet, so the GPU never goes above 53% fan speed at 2000mhz.
(same applies to OC the CPU over the 4ghz, i know can take 4.2Ghz easily but it raises the temps)

Well it's the engine that's sets the limits. Essentially after a point you're just brute forcing into the wind.

Fps limits occur for 2 reasons :

Engine limitations or a bottleneck.

@geordiejc Digital Foundry have done some clock for clock testing with Coffee Lake and Haswell here (all the chips at 4.5GHz) : https://youtu.be/CZIVaGcax70?t=750
Not much in it in some games, but huge difference in CPU demanding ones.

I have TC: Ghost Recon

Test System:
8700k STOC / 4.9GHZ
Intel LGA1151 Testbeds
Gigabyte Aorus Z370 Gaming 7
MSI Z270 Gaming M7
16GB G.Skill TridentZ DDR4-3200 CL14
Samsung 960 Evo 500GB
Corsair Carbide Air 740
Corsair HX750i 750W
Corsair H115i
1080 Ti FE

My System
4770k @ 4.3
1080 Ti Stock / OC
DDR3 1600

STOC

O/C 2025Mhz +400 mem

It seems my haswell system is doing pretty well for itself albeit the FE card is a little slower than my stoc rog 1080 ti.

This is 2 games now i've compared my system performance against 8700k with 1080 ti's @ 1080p the 4770k beats the 8700k - which is not bad for a 2013 CPU with slower ram.

AndreiD · 8 Oct 2017 at 14:11

You're still doing these comparisons when you clearly have an aftermarket, overclocked GPU?
I get that you're trying to justify your current system, but I did literally post a link above with all of the CPUs (3770K, 4790K, 7700K and 8700K) at 4.5Ghz, which should be significantly more accurate that benching by approximating a mango to a grapefruit.

Yeah for gaming it's much of a muchness, though at 1920x1080 you could get away with a 1060 card.

Warhammer 40k: Dawn of War III

Test System:

8700k
1080 FE

My system:

4770k @ 4.3Ghz
1080 Ti Stoc (Rog)

Suffered a loss here at 7fps / 12fps @ stoc / 4.9ghz respectfully.

I know you took the time to post the witcher 3 comparison, thank you.

I have an aftermarket GPU and noted that the last 2 benchmarks were vs FE cards and will be a little slower. Tthe first bench was 'like for like' both systems have 1080 ti OC strix (stoc). I also called out i put my card at stoc and oc. I'm not justifying - i'm doing a comparison with what little data i have. The hypothesis @Panos and i have is unless you game at high refresh rates @ 1080p its not advisable to upgrade yet.

I personally game @ 165hz/fps using gsync so i actually may benefit from the upgrade, but i game at 1440p. I need more 1440p benchmarks.

AndreiD · 8 Oct 2017 at 14:53

Not all reviewers use the built in benchmarks though, some use sequences of gameplay for their reviews, so unless specified it's going to be very difficult to have a 1:1 comparison.
If you game at high refresh rates then the 8700K is no doubt going to be a big upgrade over that 4770K, but it's up to you if you think the jump is warranted since you'll have to buy new RAM too.

In my opinion you can probably wait until Icelake/Zen 2 with that 4770K, but the 8700K wouldn't be a bad upgrade either if you're itching for one.

Are you happy with your current performance?

For more detail, according to that Digital Foundry review, the 8700K at 4.5Ghz compared to a 4790K at 4.5Ghz is:
38% faster in The Witcher 3
4% faster in The Division
7% faster in Assassin's Creed Unity
31% faster in Crysis 3
48% faster in Ashes of the Singularity
And if you look at the frametime graphs, it also gives you smoother frametimes, even in the games where the difference is minor.

Whether you think that difference is significant enough to warrant spending ~£700 on the 8700K+Z370 Mobo+DDR4, is up to you, but my annoyance was that comparing your own benches to reviewer ones isn't going to give you an accurate representation of the difference, hence it's always going to be a lot better to find a review that includes your CPU and go with that.

Those games would see benefit even with a 1600X/6800K/7800X etc @ 4Ghz over the 4790K @ 4.5ghz. Witcher, Crysis 3 and AOS are multithread games. Dropping there even a stock 1700 would show better perf

Thanks I wasn't aware there was an article!

My games are playable 80-120 fps @ 1440p game depending. As I have a 165hz monitor there's room for improvement . Just not sure if now is the time and sli isn't viable

The low resolution testing is not relevant to you. I suspect the percentages are calculated with the low resolution tests.

Well it's unlikely any graphics card setup will hit 165 FPS. It's even more unlikely many games will give you a true 165FPS. You will be already be getting 99% of what's possible.

From the same review, stock 8700K with 2666Mhz DDR4 compared to a 4Ghz 1700 with 3200Mhz DDR4:
25% faster in Crysis 3
39% faster in Far Cry Primal
https://youtu.be/CZIVaGcax70?t=616
Ryzen wouldn't be much of an upgrade over a 4770K/4790K.
