What to upgrade first?
It's often thought that higher resolution makes the CPU less important, but that wasn't always true. A few years ago, 4K was limited to 60Hz, and a CPU capable of 60FPS in a game engine seemed sufficient. Now, with devices like the Samsung Odyssey Neo G7 at 144Hz 4K, the focus has shifted. The main challenge is still about GPU performance for 4K, not just CPU speed.
This isn't completely accurate. The GPU needs the CPU to render frames first, and the speed depends on how quickly each can handle it. With a 4k display, if the GPU only manages 100 frames per second but the CPU can draw 400, the CPU will have to wait for the GPU. At 1080p, which is a quarter of 4k, rendering takes about a quarter of the time, so you'd get roughly 400 frames per second from both the GPU and CPU.
The best way to understand this is that both the CPU and GPU limit the frame rate based on their individual performance. At higher resolutions, the CPU usually draws frames faster than the GPU renders them, making the CPU less stressed while the GPU handles more work.
I generally don’t focus much on FPS beyond the monitor’s refresh rate. Until reaching the maximum refresh rate, the CPU needs remain consistent no matter the resolution. This applies more to esports games with 400/500fps. For AAA games, usually up to 140fps, the CPU demand for a specific game engine or game stays the same across resolutions. Some CPUs handle well and exceed 140fps, while others lag behind, similar to any CPU-heavy game.
The CPU manages the process of drawing frames by handling various tasks and coordinating data flow, while the GPU focuses on rendering each frame with visual details. Both components rely heavily on complex calculations to produce the images you see on your screen. Your question about how they work together is a great way to explore the underlying technology.
What I'm referring to applies equally to every game, not only to esports titles. The example I provided with 100/400 fps was chosen because it matched well with 1080p being one-fourth of 4K resolution.
In simple terms, the CPU creates all the lines and vertices and passes them to the GPU. The GPU then processes those complex drawings using shaders, textures, tessellation, lighting, and more for each frame. I know someone who could give a much more detailed explanation since they have deeper knowledge on these subjects.
Thank you, I'll make sure to check for an answer from @bit_user.
The available memory is quite a bit—16GB would be ideal, but you might consider boosting it to 32. For a solid upgrade, the 5800X3D seems like a strong choice this year. The RTX 3070 has room for improvement since it only offers 8GB of VRAM, which starts to limit performance at higher resolutions like 1440P, though it still delivers good results. An RX 7800 XT or RTX 4070 would also be beneficial, but the gains would be modest (~30%). To see a more substantial improvement, you’d need something like an RX 7900 XT, RX 7900 XTX, or RTX 4080. These options could double your current gaming capabilities. Honestly, you’re in a bit of a bind—waiting a year on the GPU might be the best approach unless you spot a great deal on an RX 7900 XT, RX 7900 XTX, or RTX 4080. Additionally, you can still run FSR or FSR 3 with your Nvidia graphics card if the game supports it; this is possible thanks to the open standard.

Thank you for your input. I have 32GB of RAM and feel comfortable with that amount. We're aligned on this. I'm considering getting the 5800X3D because it offers a good value boost, making better use of my existing components. I'll keep an eye on the Nvidia updates and aim for a 4080 once the Supers are released, but we'll adjust as needed. No rush to buy for Black Friday. Appreciate your feedback!
