Hi guys

Will be soon grabbing a 1080ti to run 3600x1920 60hz but i am concerned about how much of a bottleneck the i5 will be.

I can get the cpu to 4.4/4.5 would that help get the most out of the 1080ti. Would rather avoid grabbing the i7 if i could.

Main games which i would be playing would be arma3 and squad.

TIA
 
I think your resolution will help out quite a lot there. Overall, I think it will be a pretty good experience (generally speaking).

The arma games are CPU bound, though how well a title like that plays out at such a high resolution, I don't know, but I think you should be okay.
 
There is only so far you can say that a high res takes the bottleneck and places it from the CPU to the GPU.

Take a 1080ti, start with the fastest CPU in the planet and play say BF1 at 4k. Then proceed to go backwards in terms of CPUs. All the way down to the worst celeron or atom processor. Eventually your find you hit a point where performance falls off a cliff as the CPU is simply no longer fast enough for the core logic of the game as well as fast enough to feed the GPU.

In other words your i5 will be OK. But just OK. It's still a huge bottleneck on the 1080ti. Also limited to only 4 threads.

Basically the GPU is important for max fps. But it's your CPU that determines your minimums and to some extent your average.

Unless you have plans to upgrade CPU I would advise against it.

Especially as the main game you mention is ARMA. Which is basically cpu bound.

My old 3570k at 4.5Ghz was a bottleneck for a 970. So a 4670k is a huge bottleneck on a 1080ti!

How about a 4770k, I've only got it clocked to 3.8ghz but I could get it higher, it's got the cooler to go higher (Phanteks TC14PE) I just didn't have the patience to run the benchmarks needed to test for stability so just went Intels auto boost and it has been okay for my needs with my 390, tomorrow I'll have a 1080Ti however

Bear in mind I'm currently only playing at 1080p, likely going to 1440p but it'll be when the monitors with G-sync get a bit more reasonable in price, 4k I really have no interest as it's still early days in that realm and prices + performance aren't there yet
 
Opposite ends there, I have both games myself. The UE4 engine for Squad is new and being updated regularly with new features, I think it'll make good use of many threads should run fine. Arma is an old engine apparently and relies on the highest speed possible on 1 or 2 threads. Such a high res means the GPU is useful even if the game were leaning on the cpu too much like Arma might, I imagine you'd get more fps with 7700k at 5ghz but not a great deal also I think the server determines your fps somehow. Theres a russian test site that does these benchmarks best on various setups and they do milsims.

The switch from 1080p to 4K is quadruple the load so its like throwing a bag of concrete on the graphics card :D
1080p is a cpu test on arma maybe, I saw a vid of 4k at 60fps and they were recording at the same time but I forget their config used
 
I have a 4690k with a 1080Ti and I don't notice any performance hit?

How much difference are we talking here between an 4690k and the 7640x? surely it can't be more than 20-30fps? or can it..

Latest i5. No one buys an i5 for gaming any more. It's a bottleneck neck already. Take BF1 for example.

i5 was the go to chip for gaming in 2012. Not recommended in 2017.
 
Thanks all

Will see if i can get by with the i5 for now.

If i am able to stay around the 60fps mark with only slight stuttering i could bare that.But can definitely see that would need a better cpu for the newer titles that are out.

I see that's interesting. I'm happy with my 4690k, but I will probably go for an i7 next time.

I just found this review - http://www.anandtech.com/show/11549...-the-new-single-thread-champion-oc-to-5ghz/16

In those benchmarks at 4k, the i5 7600k and 1080 perform almost the same as the 7640x and beats the Ryzen CPU's quite a bit which is pretty weird, surely that can't be right?

Anecdotal evidence is some people are complaining of stutter with an i5.

Of course higher ipc and frequency helps.

More to it than just raw fps. Frame times being one of them.

For now a fast i5 is fine. But it soon won't be.
 
I've got a 4690 (no 'k' therefore not overclocked). I've got a 1080ti and haven't noticed any performance issues, though I've mainly been using it for VR (i.e. Elite Dangerous).

The non-VR games I've played (Guild Wars 2, Far Cry 3 and Firewatch) seem to run fine, though I'm not sure how having 3 monitors affects the load balance re GPU/CPU. I have heard that BF1 can be bottle-necked by the 4690, though I can't comment as I don't play it.

I'm not looking to upgrade the CPU at the moment as I'll probably wait for the next generation of VR. I'll build a new system if/when that comes out.

But to cut a long story short, my 4690 is probably at it's limit, but it's OK for the short term.

(Edit - just realised the OP referred to 4670k, not 4690. I'm not sure how different they are...)
