Rust
A true test for system memory. Procedural maps can exhaust RAM quickly; 16GB is the minimum, and 32GB is recommended. CPUs with 3D V-Cache (AMD X3D) offer massive performance gains here.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 179 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 148 FPS. At 4K, all settings exceed 77 FPS.
The Radeon RX 7900 XTX is 182% above the recommended GPU (GeForce GTX 980) for Rust. The Ryzen 7 7800X3D is 180% above the recommended CPU (Core i7-4790K).
No major FPS-ceiling mismatch detected. The Radeon RX 7900 XTX and Ryzen 7 7800X3D stay close in effective frame-generation ceiling across the tested resolutions and quality settings.
Approximated average price on current market:
Combo price: $1308.13. At 1080p Ultra, this combo delivers 179 FPS, equivalent to 0.14 FPS per dollar.

This chart answers a simple question: which upgrade is more likely to increase FPS first? In this case, there is no clear winner.
The largest gap still appears at 1080p Medium, where the Radeon RX 7900 XTX reaches about 235 FPS, while the Ryzen 7 7800X3D still has headroom up to roughly 257 FPS.
That means neither part is consistently hitting its ceiling far ahead of the other. Across all tested settings, this pairing is GPU-limited in 12 out of 12 cases, CPU-limited in 0, and balanced in 0.
Overall, this is a balanced combination in this game.
Neither the Ryzen 7 7800X3D nor the Radeon RX 7900 XTX stands out as the consistent limiter in this game, so the better upgrade depends more on your target settings than on one obvious bottleneck.
This chart shows which upgrade is more likely to unlock more FPS in each tested setting. The lower line represents the part that reaches its limit first. When the CPU and GPU lines stay close together, the system is more balanced. When the gap widens, one component is more clearly holding the other back. Hover any setting to inspect it.
The lower line is the current limiter. The closer the two lines are, the more balanced the CPU and GPU are for this game.
Each line represents an estimated FPS ceiling for one component, rather than live usage alone.
To estimate the CPU ceiling, we pair the Ryzen 7 7800X3D with GeForce RTX 5090, our current GPU anchor. To estimate the GPU ceiling, we pair the Radeon RX 7900 XTX with Ryzen 9 9950X3D, our current CPU anchor.
The lower line indicates the current limiter, since that component reaches its FPS ceiling first. In most scenarios, that is also the part most likely to deliver the bigger performance uplift if upgraded first.
The percentage shown represents the gap between the two ceilings. In practical terms, it shows how much of the stronger component's potential is left unused because the weaker one becomes the bottleneck first.

Yes, the Ryzen 7 7800X3D paired with the Radeon RX 7900 XTX can run Rust smoothly up to 4k achieving around 77 FPS at Ultra quality. Your GPU is 182% above the recommended specs, and your CPU is 180% above the recommended requirements.
This CPU + GPU combo costs approximately $1,308.13 ($378.13 CPU + $930 GPU). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
This setup is already well-balanced for Rust. In the Performance Limiter Analysis, neither side consistently defines the maximum FPS across the tested presets. Across all tested settings, the distribution is 12/12 GPU-limited, 0/12 CPU-limited, and 0/12 balanced. In practice, this pairing behaves as a well-balanced combination in this game. Because of that, upgrading only one component would usually bring smaller gains than improving the overall pairing.
Rust does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Rust requires at minimum a Core i7-3770 (CPU) and GeForce GTX 670 (GPU) with 10 GB RAM and 25 GB (SSD) storage. For the recommended experience, you need a Core i7-4790K and GeForce GTX 980 with 16 GB RAM. Your Ryzen 7 7800X3D and Radeon RX 7900 XTX both exceed the recommended specs, so you're well-positioned for a great experience.
These Rust FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
