Question Should I upgrade CPU or GPU

[Axiss]

Hello I am in the market for a hardware upgrade to improve framerate In games especially in battlefield v. I have to run the game at low setting on 1080p at 60hz and I get around 40-50 FPS and it spikes heavily around 30 in combat.
My specs are a gtx 1060 3gb and a I5-4570. 12gb ddr3 ram 1600 MHz.When I run the game my cpu is at 100% load on low settings.
I was debating if I should upgrade the gpu to a gtx 1660 or upgrade the cpu to a i7-4790k or just upgrade motherboard ram and cpu for a Ryzen 5 2600. Which upgrade will give me better frames??

Ideally both? Wait for next zen CPUs though

Prob get a better Intel CPU if you don't want to replace the motherboard since the CPU u said is always at 100%. So I'm guessing that the GPU is bottlenecking the CPU. If I was you, I would sell the motherboard with ram and CPU on it so I can either get the ryzen 5 2600 or wait for the 3rd gen of amd ryzen. Then pair it with 16 GB of at least 3000 MHz ram and Gtx 1660 ti is a good choice

If I can only do one of the two which should I do

Probably CPU since it can't keep up with the GPU

take a look at gpucheck it lets you change cpu/gpu and gives estimated frames.

I looked on there. You should be getting around 140fps. that cpu is only -6.7fps compared to 8700k.

I'd make sure your memory is running dual channel and check your cpu temps. If your cpu cooler isn't seated well or doesn't have paste on right you can get throttled, around 100C is real bad. 12GB ddr3 seems suspect to me. you need two identical sticks to run dual channel.

HWMONITOR can test both.

Probably CPU since it can't keep up with the GPU, you should get more than 60 fps when playing low setting on BF 5 with Gtx 1060.

CPU but wait for the new CPUs to come out.
