NEED HELP on upgrading my PC for Rainbow Six Siege

[Haps]

Hey everyone! I need help on how to upgrade my PC based on the problems below. Your help would be greatly appreciated!


Here are my PC specs:

CPU: Intel(R) Pentium(R) Gold G5400 CPU @ 3.70GHz 3.70GHz
GPU: NVIDIA GeForce GTX 1050 Ti
Motherboard: Gigabyte H310M DS2
PSU: DeepCool DE500 V2
RAM: 8.0 GB
SSD: 118 GB (101/118 GB used)
HDD: 900 GB (I don't use this)



R6 Siege Settings:

Graphics Settings: Everything on LOW

Resolution: 1280x1024 (I run this because my monitor has 75hz option for this resolution)



PROBLEMS:

- CPU usage is at 100% (does this mean my GPU is bottlenecking?)

- On average, my FPS in-game jumps from around 80-100 depending on whats happening, but at times it randomly drops to 55-60 for a few seconds which is very irritating.

- Discord becomes very choppy when running R6 (I can't hear and speak to people clearly in Discord, other than that, when I run R6, Discord would crash and I need to restart it)

- Additional info: I have already tried tweaking every windows and NVIDIA setting possible to make the most out of my PC!



I haven't upgraded yet since I built the PC but I think now is the time, except I have no idea which part should I upgrade and why, which is why I need your help!
For a start, I just want to know which part I should upgrade first in order to solve the FPS dropping problem, but later on in the future, I would also like to play the game at 144hz!



Some people say that I should upgrade my CPU, and I'm thinking about i5-9400f? Some people also told me to upgrade my RAM but they don't tell me why, so I really have no idea!
SO GUYS, WHICH PART SHOULD I UPGRADE FIRST AND WHY?

[_I_]

cpu first, the g5400 is a dual with ht (similar to older gen i3)
newer games can use more cores/threads, will really help with background tasks while gaming
ie. discord, chrome, all other windows hidden tasks

it can take a i3/i5/i7 8xxx-9xxx

choices are here

i3 9100f has 4 real cores, or i5 9600k has 6 (your board will not allow overclocking, but still make use of its higher base and turbo clocks)

1. no... your cpu is too weak for games that use more than 2 cores...

2. if you run anything in background it is too much

3. your ram is also on its limit just see above

how much money do you have to upgrade?

I used to play rainbow six siege several years ago and it ran well on dual-core i3.
Has anything changed since than?

Thanks for the help! So are the CPUs you mentioned better than the i5-9400f? I also plan on upgrading my GPU later on in the future, will the i5-9400f be enough?

Right now I can only afford the price of a i5-9400f, I also need to upgrade ram in your opinion?

Honestly - you are making things worse with your settings.
Set resolution to native, cap fps to refresh, close all background applications (if you have any other device that can run discord - run it there) and judging by what you describe you should get consistent 60FPS. Which will be way, way better than inconsistent 55-100FPS on 75Hz refresh scaled resolution screen.
If you want high refresh "in future" be aware that you will need high-end hardware for it and plan accordingly. You will probably have to replace PC alltogether.

Thanks for the advice, but if I would want it to run at 75hz stable, will upgrading my CPU to a i5-9400f solve all my current problems now, and be a good enough CPU if ever I were to upgrade my GPU in the future? (In the future, I want to run the game at 144fps)

8400/9400/f have slower base clock with 6 cores no ht
imho spend the $20 more for the higher clocks of the 9600k
the g5400 cooler will work on it 55-65w isnt a huge jump, and without oc it will run cool
or you can lower vcore if its running warm

[L37]

i5-9400f is mostly fine now, and should fix your issues, but with 6 cores and no HT it is already "not great" and may have similar issues to your pentium in not-so-distant future. Do not expect it to be good for running games at 144fps.

Thanks for the response! Btw, as a new guy to PCs, mind telling me what higher clocks do and also what is hyper-threading?

[L37]

Again, 6 core no HT. Higher frequency is nice, for now it will be fine, but how it will handle new games - nobody knows. With how things are progressing, 16c32t mid-range cpu-s and such, i would not expect it to be good for significant amount of time.
However, with intel you basically have no choice...

[_I_]

games are still more dependent on a single core, renderers/ai ect.. can run on others but if the main game thread can not keep up, the game will not be smooth

[L37]

Sure, and that will probably remain true for foreseeable future. But if all those extra stuff in separate threads causes 100% load for whole CPU game will not be smooth either.
Seen this on relatively new 4c4t and 4c8t cpu-s already for some games, 6c6t is still fine, but who knows for how long?

[Komrade]

OP for now set your in-game resolution back to 1080p native, lowering it to 720p is making your already weak CPU work harder, you’ll get better performance upping it.

[Zireth]

Did a bottleneck test, your CPU is too weak for your GPU, but I don't believe that is the main issue.
Apparently there is an issue with the game that makes CPU usage go to 100% and here's a method to fix it: https://www.youtube.com/watch?v=C0NS82kCHH8

Don't go to 720p for 75hz, stick with 1080p. As for a possible CPU upgrade, Ryzen 3600 with a MSI tommahawk max and 16gb of ram. Here's a list mate: https://pcpartpicker.com/list/rYR8WD
