My current system has a Ryzen 7 5700G, an RTX 3060 with 12GB of VRAM, and 32GB of DDR4 memory. I mainly want better performance in CPU-heavy games such as Rust. I'm considering upgrading to a Ryzen 7 5800X3D, but I'd rather stay on AM4 because moving to AM5 would also mean buying more expensive DDR5 memory. Would the 5800X3D provide a noticeable improvement, and is it worth the cost with my current graphics card?

I’d compare the actual price before buying. At a high price, the 5800X3D is difficult to justify for a system with an RTX 3060, especially if you mostly play GPU-limited games. At a reasonable used price, it’s a good drop-in AM4 upgrade and gives you more headroom for a future graphics-card upgrade. Otherwise, saving toward a newer GPU or a later full platform upgrade may provide more noticeable results.
Yes, Rust is the kind of game that can benefit from the 5800X3D’s much larger L3 cache. Compared with the 5700G, you should see better frame-time consistency and stronger performance in CPU-limited situations. The improvement can be substantial depending on your settings and location, though the exact FPS increase will vary.
Whether it feels noticeable depends on your resolution, graphics settings, monitor refresh rate, and whether you’re currently CPU-limited. You may not see a huge increase in average FPS if the RTX 3060 is already the bottleneck, but the 1% and 0.1% lows should improve, which can make busy areas and large fights feel smoother.
Since you already have an AM4 motherboard and DDR4 RAM, an X3D chip is a sensible upgrade without rebuilding the whole platform. A 5600X3D can be a cheaper alternative where it’s available, and a 5500X3D may also be worth considering. Both should pair reasonably well with an RTX 3060.
