Hi
As the title says I have:
i5-4460
KFA2 1080
20gb RAM
win10

I have been trying games out with the new gpu and noticed if I ramped the witcher 3 up I was getting decent fps, however I was discussing with someone and they said my cpu was bottlenecking & I should upgrade.
Is this the case? if so Im looking at the i7-4790k really.
UPDATE: apologies I am running it at 1080 not 4k.


Thanks in advance

Just run Task Manager -> Performance -> Resource Monitor while gaming. That will give you the CPU and memory utilization.
Open also an instance of GPU-Z - that will give you the GPU utilization.
Play the game for a while a that quickly Alt-TAB and capture the screen. The instantaneous utilization numbers will drop but you can see the history. If you have two screens you can see them in real time.
If in your case nothing is pegged at 100%, that's all good.

This is Fallout 4 in 1920x1080, Ultra Settings, Weapons Debries on Ultra, running on a GTX 960 and Xeon X5675... Fluid play.
The second GPU is dedicated to PhysX, will go higher when is a lot of explosions on the screen, for this shoot I forgot to throw some grenades...

your I5-4460 will bottleneck your GTX1080 but if you are getting good framrates at your resolution whats the point? there is always going to be a bottleneck on your computer somewhere be that your GPU being bottlenecked by your CPU or vice versa but it doesn't matter as long as you get good frame rates.

Its your CPU not being able to handle the GPU and whatever else the CPU itself needs to do for the game.

I replaced my i5 4460 just a week ago due to 100% usage in Fallout 4 and Witcher 3. I now have an i7 4790K and I have no bottleneck in anything anymore, I have a MSI GTX 970 4GB thou but will be getting a MSI GTX 1080 8GB next year.

You could worry about a bottleneck if you didn't get the desired experience/quality from your hardware. Are you getting the optimal performance from your hardware? does it give you fluid gaming experience? if yes, you do not need to worry
