Need help upgrading my PC (lemmy.world)

Hello everyone!

I'm posting this because I need help upgrading my PC components. However, I don't know where to start.

Here are my current specs:

Operating system : Nobara Linux

Processor : AMD Ryzen 5 5600, 6x 3500 MHz

CPU cooler : Deepcool Gammaxx C40

Graphic card : ASUS Radeon RX 6800, ASUS TUF-RX6800-O16G-GAMING, 16 GB GDDR6

Motherboard : ASUS TUF B450-PLUS GAMING II

RAM : 32 GB DDR4-RAM, Dual Channel (4x 8 GB), 3200 MHz

Storage :I have several SSDs so that's fine

Case : Deepcool CL500, black.

Power supply : 750 Watt MSI MPG A750 GF, 90% efficiency (80 Plus Gold certified)

I would like to point out that I play on a 2k 144hz 27" monitor and I want to stick with full AMD because it's more convenient for me on Linux.

Even though I don't think there's a bottleneck, I'm looking to improve my setup primarily because I play The Finals in 2k, and with the graphics on low, I often drop below 80 fps at times (I would like to stay at 120fps).

Thank you for reading!

PCIe scaling isn't really significant. With a 4090 you lose 2% going to 3.0 instead of 4.0 at 1440p per techpowerup https://www.techpowerup.com/review/nvidia-geforce-rtx-4090-pci-express-scaling/28.html

He is using and instead of nvidia and linux instead of windows but his card is so much slower that the drop should be a lot less

From some other benches people have posted, ultra settings at 1440p he should be averaging 180 fps then even if he is using 3.0 x4 due to lane splitting from ssds which is roughly equivalent to pcie 1.1 x16 then it's probably still not the main culprit
