Bottleneck check or cpu suggest please


Aug 11, 2017
I have gtx 760, I am currently looking to buy new cpu. I was looking at i5 7600k, i checked on the bottleneck calculator website it said %18 bottleneck. Will that effect me much and is that true or should i buy another cpu if so which cpu would be right? thanks for advance. ( I already have the gpu and power supply)

FIXED. No bottleneck here with way better perf.
What is your current build?

My stock approach to this perennial question:
Some games are graphics limited like fast action shooters.
Others are cpu core speed limited like strategy, sims, and mmo.
Multiplayer with many participants tend to like many threads.

You need to find out which.
To help clarify your CPU/GPU options, run these two tests:

a) Run YOUR games, but lower your resolution and eye candy.
If your FPS increases, it indicates that your cpu is strong enough to drive a better graphics configuration.
If your FPS stays the same, you are likely more cpu limited.

b) Limit your cpu, either by reducing the OC, or, in windows power management, limit the maximum cpu% to something like 70%.
Go to control panel/power options/change plan settings/change advanced power settings/processor power management/maximum processor state/
This will simulate what a lack of cpu power will do.
Conversely what a 30% improvement in core speed might do.

You should also experiment with removing one or more cores. You can do this in the windows msconfig boot advanced options option.
You will need to reboot for the change to take effect. Set the number of threads to less than you have.
This will tell you how sensitive your games are to the benefits of many threads.
If you see little difference, your game does not need all the threads you have.

It is possible that both tests are positive, indicating that you have a well balanced system,
and both cpu and gpu need to be upgraded to get better gaming FPS.

this is a very useful comprehensive post. Covers all bases to establish if there is a bottleneck. I'd like to quote it for future posts if that's okay?

Not really needed for the OP though. That CPU will not bottleneck that GTX760.

Happy to have the reply quoted.
This question comes up so much that I thought I would try to document a reasonable canned approach to the question.

As to the OP question, I5-7600K with an overclock is unlikely to be a bottleneck to a GTX760, or for any other single card for that matter.


Why don't you make it a sticky on Tom's. Or can we still do that?

I have no idea about a sticky.
But I use the text as a framework and edit it for different situations.
