Is the RTX 5070 Ti a good choice with my Ryzen 7 3800X?

It also depends on your gaming resolution. If you're at native 4K, the CPU won't be as critical. But if you're playing at lower resolutions with upscaling, the CPU could be a bigger factor. Make sure to test this out to see where you're at.

What resolution are you playing at? If you're used to 1440p+, it's likely that your GPU is the one being stressed rather than your CPU. There's a test from Hardware Canucks that showed the 5070 performed comparably with a Ryzen 3600X in various games, but there are exceptions in CPU-heavy titles like Warhammer 40k and Baldur's Gate 3.

The performance really depends on the games you're playing. The 5070 Ti will definitely work with your Ryzen 7 3800X, but in some CPU-intensive games, you might hit a bottleneck. One way to mitigate that is by cranking up the graphics settings so that the GPU is the limiting factor instead. That should help minimize stutters too!

Given that you're gaming at 2K, titles like Battlefield and R6, along with doing 3D renders, the 5070 Ti should improve stability and performance. You might not be looking for a huge FPS jump, but it should help reduce the stuttering and drops you're facing, especially aiming for a stable 120 fps.

The RTX 5070 Ti would definitely give your gaming performance a nice boost. While the CPU won't matter as much at higher resolutions like 4K, be prepared to upgrade your CPU down the line for maximum performance. It's a solid choice!
