I checked your setup after the GPU upgrade and want to make sure your CPU isn’t limiting performance.
I own an i7 9800x, still in its original state. I previously had a GTX 1070 which I swapped out for an RTX 3070. I made some adjustments, reduced the voltage and added a bit more memory. I ran a few tests to see how it performed and noticed higher FPS and less heat each time (cooling was my main focus). I came across a video showing someone using a 4790k with a 3080, who saw a big boost in FPS after upgrading the CPU to a 12700k. My current CPU is newer than theirs, but checking cpubenchmark.net shows only a slight improvement over the 4790k's single-core score. I've been told single-core performance matters a lot for gaming. What are your thoughts? Am I holding my GPU back? Would upgrading the CPU really make a big difference?
The 9800X will likely hold the 3070 back somewhat, but the outcome depends on your chosen games, display settings, and desired frame rates. It runs on a Skylake-X CPU with Mesh interconnect, offering solid performance compared to other Skylake models. While it's still an capable 8-core processor, expectations for speed are higher than earlier Skylake variants. You might see improvements with newer architectures like Alder Lake or Zen 3, but at this stage, those options seem more promising. The decision to upgrade hinges on your performance goals and other factors such as PCIe expansion. If you're happy with the current setup, overclocking could be an option before replacing it entirely. Test it with your games first and adjust accordingly.
I selected the incorrect platform because I got a PC in 2017 from a parts site when I had limited knowledge about computers. I didn’t understand much at first—just that GTX 10xx cards were new and an i5 was a mid-range processor. It was a convenient choice at the time, as my previous machine had a GTX 460 and an older CPU. Upgrading later revealed I had little room for further changes with the motherboard, and the Xtreme CPUs weren’t designed for serious gaming. With limited funds, I went for an upgrade from an i5 7640x to an i7 9800x without much thought. Initially, the performance difference was minimal—only a few frames per second. After upgrading the GPU, things improved significantly; using the 1070, I could run Cyberpunk smoothly at medium settings and hit around 40fps. With the 3070, I achieved 80 to 160 fps depending on the load, especially at 1080p without RT. I’m satisfied with the current performance, though I find it frustrating that my CPU seems to limit the GPU’s potential. I can’t overclock it because it already runs quite hot, often around 80°C.
It depends on what you're aiming for—whether you want to match a 4790k or surpass it for better performance.
It’ll be significantly improved compared to a 4790K in most modern titles. As mentioned earlier, your 8-core processor is still decent, though you'll notice a performance gap versus newer chips. Overall, it’s acceptable—performance varies based on frame rates, resolution, and the specific games. As @PDifolco pointed out, 1440P should work well, but high refresh rates might cause some issues in certain titles. Personally, I’d prefer to stick with it and make the most of its capabilities. Your setup is solid, handling most tasks smoothly. The focus should really be on what you want to achieve, not how fast it could be. =)
Higher quality settings often place more demand on the GPU since they require rendering more pixels. Adjusting graphics to Ultra usually increases CPU strain too, especially when dealing with complex elements like crowd density in games such as Witcher 3 or Cyberpunk. The impact isn't uniform—some settings can also stress the CPU more due to increased draw calls and processing needs. It's not a one-size-fits-all situation. Personally, I usually stick to slightly lower resolutions for better performance, unless the visual quality is crucial for the experience. For games like Battlefield 5, I prioritize visibility over grass appearance, since it doesn't significantly affect target acquisition. Ultimately, the decision depends on your gaming goals—whether you're focused on immersion or competitive play. What matters most is finding the right balance that suits your needs. Keep in mind, opinions vary widely based on hardware and game specifics. Different engines behave differently, and what works for one person might not work for another. I tend to disable or lower settings that cause issues like motion blur or color distortion until my display meets its refresh rate, which is around 144Hz. Most of the time, lower settings still deliver great visuals.
