Performance Report
At 1080p, all quality settings exceed 513 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 385 FPS. At 4K, all settings exceed 256 FPS.
The Quadro RTX A6000 is 17711% above the recommended GPU (GeForce 7600) for Left 4 Dead 2. The Ryzen 7 9800X3D is 1724% above the recommended CPU (Core 2 Duo 2.4GHz).
At lower resolutions (1080p (low/medium), 1440p low, 4k (low/medium)), the Ryzen 7 9800X3D sets the FPS ceiling. As graphical load increases at (1080p ultra, 1440p ultra, 4k ultra), the Quadro RTX A6000 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p high, 1440p (medium/high), 4k high.
Approximated average price on current market:
Combo price: $3965.38. At 1080p Ultra, this combo delivers 513 FPS, equivalent to 0.13 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages. Adjacent heavier settings are lightly stabilized to remove prediction jitter that would otherwise create impossible reversals.
At 1080p low, the Ryzen 7 9800X3D sets the ceiling at about 820 FPS, while the Quadro RTX A6000 could reach 1026 FPS. In this scenario, the CPU limits the GPU potential by 20% (FPS gap: 206 FPS). Overall distribution: CPU limits 6/12 cells, GPU limits 3/12, balanced 3/12.
Your Ryzen 7 9800X3D is the limiting side in the heaviest mismatch. This means part of the Quadro RTX A6000 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 20% | CPU Limits GPU 7% | Balanced | GPU Limits CPU 14% |
| 1440p (2K QHD) | CPU Limits GPU 20% | CPU Limits GPU 6% | Balanced | GPU Limits CPU 16% |
| 4K (Ultra HD) | CPU Limits GPU 20% | CPU Limits GPU 6% | Balanced | GPU Limits CPU 16% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings and then monotonic-smoothed across heavier presets and resolutions, not generic utilization heuristics.

Yes, the Ryzen 7 9800X3D paired with the Quadro RTX A6000 can run Left 4 Dead 2 smoothly up to 4k achieving around 256 FPS at Ultra quality. Your GPU is 17711% above the recommended specs, and your CPU is 1724% above the recommended requirements.
This CPU + GPU combo costs approximately $3965.38 ($465.38 CPU + $3500 GPU). Your Ryzen 7 9800X3D provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end processor with a significantly better value rating. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #4 for value).
Your Ryzen 7 9800X3D is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Left 4 Dead 2 performance right now. CPU fully utilized at: 1080p low, 1080p medium, 1440p low, 4k low, 4k medium. GPU-limited at: 1080p ultra, 1440p ultra, 4k ultra.
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 Quadro RTX A6000 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.
