This chart answers a simple question: which upgrade is more likely to increase FPS first? In this case, the answer is clearly the GPU.
The largest gap appears at 1080p High, where the Radeon Pro 5700 reaches about 257 FPS, while the Ryzen 7 9800X3D still has headroom up to roughly 710 FPS.
That means the Radeon Pro 5700 is hitting its performance ceiling first, leaving a 64% gap versus the Ryzen 7 9800X3D's available headroom in the most unbalanced scenario. Across all tested settings, this pairing is GPU-limited in 12 out of 12 cases, with 0 CPU-limited and 0 balanced results.
Overall, this is a clearly GPU-bound combination in this game.
The Radeon Pro 5700 is consistently the limiting part in this game, so upgrading the GPU is more likely to deliver a larger FPS gain than upgrading the CPU.
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 9800X3D with GeForce RTX 5090, our current GPU anchor. To estimate the GPU ceiling, we pair the Radeon Pro 5700 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 9800X3D paired with the Radeon Pro 5700 can run Left 4 Dead 2 smoothly up to 4k achieving around 129 FPS at Ultra quality. Your GPU is 8860% above the recommended specs, and your CPU is 1724% above the recommended requirements.
This CPU + GPU combo costs approximately $715.38 ($465.38 CPU + $250 GPU). Since the GPU is the main limiting factor, investing in a stronger GPU will improve your framerates and overall value. For example, upgrading to the Quadro RTX 4000 (móvel) for around $900 (Rank #105 for value) could deliver noticeably better performance.
For Left 4 Dead 2, upgrading the GPU would usually give you the most noticeable improvement. In the Performance Limiter Analysis, the Radeon Pro 5700 is the side that most often caps the frame rate, while the Ryzen 7 9800X3D still has additional headroom in the tested presets. The main bottleneck appears on the GPU side. The largest gap shows up at 1080p High, where the GPU reaches about 257 FPS while the CPU still has headroom up to roughly 710 FPS. Across all tested settings, the distribution is 12/12 GPU-limited, 0/12 CPU-limited, and 0/12 balanced.
Left 4 Dead 2 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.
Left 4 Dead 2 requires at minimum a Pentium 4 3.0GHz (CPU) and GeForce 6600 (GPU) with 2 GB RAM and 13 GB storage. For the recommended experience, you need a Core 2 Duo 2.4GHz and GeForce 7600 with 2 GB RAM. Your Ryzen 7 9800X3D and Radeon Pro 5700 both exceed the recommended specs, so you're well-positioned for a great experience.
These Left 4 Dead 2 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.
