I'm planning to upgrade my RTX 2080 to an RX 9070 XT and move from 1080p 144Hz to a 1440p monitor with a 200Hz refresh rate. I currently use a Ryzen 7 3800XT on AM4 and am unsure whether it will hold back a GPU of that class, especially in CPU-heavy games or when aiming for high frame rates. If I stay on AM4, the Ryzen 7 5800X3D is the upgrade I'm considering, but it costs around $500 CAD where I live. Would the improvement over the 3800XT be noticeable enough to justify that price, particularly in frame-time consistency and 1% lows, or would I be better off keeping the current CPU?

Before buying anything, get the monitor and test your current system with the games you actually play. The RTX 2080 may still be adequate at 1440p depending on your settings. If you do upgrade the GPU, you can monitor GPU usage and frame-time graphs to see whether the 3800XT is holding it back.
The 5800X3D is one of the strongest gaming upgrades available for AM4 and pairs well with a 9070 XT. It should provide much better minimum frame rates and smoother performance than the 3800XT, rather than just a small average-FPS improvement.
If the 5800X3D is too expensive, look for a discounted 5700X3D or another affordable AM4 X3D chip available in your region. Those options can offer much of the gaming improvement for less money, though availability and pricing vary. Avoid switching platforms unless the total cost makes sense, since an AM4 X3D upgrade lets you keep your motherboard and memory.
The biggest benefit of moving from Zen 2 to a 5800X3D is often smoother frame delivery: better 1% and 0.1% lows, fewer stutters, and smaller FPS drops. That quality-of-life improvement can be very noticeable even when the average FPS increase doesn’t look dramatic.
The answer depends heavily on the games you play and the frame rate you’re targeting. At 1440p, the GPU will often be the limit, but competitive games, simulators, and other CPU-heavy titles can still expose the 3800XT. If you want to stay near 200 FPS, the CPU upgrade is more useful than if you’re happy around 100–144 FPS.
That’s what I’m trying to figure out—whether the improvement is large enough to justify roughly $500 CAD, rather than only being a minor increase in average FPS.
