Need help figuring out if CPU will bottleneck GPU

[vosix]

Hey everyone, right now I'm deciding whether or not to upgrade my gpu from a 960 to a 1070, but the problem is I don't want my i5-4590 (3.3ghz) to bottleneck it to oblivion. I'll be aiming for 144fps as I have a 144hz monitor. Any help is appreciated, thank you.

It will. What games do you play?

It depends on the game you're playing. If the CPU utilization is maxed out or appears to flat line at a certain point (an easy way to check this is to reduce the CPU affinity of one or two CPUs and see if the performance drops linearly), then your CPU is running the software at its limit and may potentially limit the performance of a GPU.

 

However, don't take this to mean that upgrading to a GTX 1070 means you will get zero performance improvement. When I went from an i5-4670K that was overclocked to an i7-6700, both had a GTX 980 and in a lot of tests, the i5 performed a bit better. But when I upgraded the video card to a GTX 1080, when paired with the i7-6700, it was still a massive upgrade.

It will be a bottleneck, but upgrading your cpu will mean a new platform alltogether like MOBO, RAM ect

not really, a 4790K would be an amazing chip to pair with a 1070.

 

anyway, @vosix, as stated above you should check how the utilisation is on your chip when running the games you want to see the bettleneck in. bottlenecks are very depending on the software side of things aswell, so eventough you might get one on paper it might not be the case in practice.

I think it really depends on the game.
I'm still running a 4670k (at stock) and it's no slouch.

I'm running a Gtx 1080 with a 144hz monitor with that cpu and I'm very happy with the performance.

You should probably sell your cpu and get an used 4790. Though it will depend from game to game, its not the same getting 144 fps on dirt 3, than PUBG

@everyone I'm playing games like pubg, overwatch, arma 3, rainbow six, mostly just AAA titles.

Arma 3...  144hz... lol.

 

i5 4590 should be fine for a 1070 in many cases, especially if you use DSR instead of MSAA.
