This tactical shooter uses the AnvilNext 2.0 engine and features procedural environmental destruction, which can be taxing on the CPU. The Vulkan API helps older hardware maintain performance by better utilizing available resources. Siege is sensitive to RAM speed and latency. The HD Texture Pack can push VRAM usage over 6GB, so cards with 8GB or more are recommended for the best visual experience at 1080p or 1440p.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, frame rates range from 36 to 72 FPS depending on quality settings. At 1440p, frame rates range from 25 to 48 FPS. At 4K, frame rates range from 10 to 19 FPS.
The GeForce RTX 4090 is 611% above the recommended GPU (GeForce GTX 670) for Rainbow Six Siege. The Core i7-3960X Extreme Edition is 89% above the recommended CPU (Core i5-2500K).
The GeForce RTX 4090 sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Core i7-3960X Extreme Edition still has additional frame-generation headroom.
Approximated average price on current market:
Combo price: $1799. At 1080p Ultra, this combo delivers 36 FPS, equivalent to 0.02 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k medium, the GeForce RTX 4090 sets the ceiling at about 23 FPS, while the Core i7-3960X Extreme Edition has headroom up to 119 FPS. In this scenario, the GPU limits the CPU potential by 81% (FPS gap: 96 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce RTX 4090 is the limiting side in the heaviest mismatch. This means part of the Core i7-3960X Extreme Edition frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 64% | GPU Limits CPU 70% | GPU Limits CPU 67% | GPU Limits CPU 72% |
| 1440p (2K QHD) | GPU Limits CPU 71% | GPU Limits CPU 75% | GPU Limits CPU 74% | GPU Limits CPU 78% |
| 4K (Ultra HD) | GPU Limits CPU 76% | GPU Limits CPU 81% | GPU Limits CPU 80% | GPU Limits CPU 80% |
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, not generic utilization heuristics.

The Core i7-3960X Extreme Edition and GeForce RTX 4090 will struggle to run Rainbow Six Siege at smooth framerates. At 1080p Ultra, you can expect around 36 FPS which is classified as "playable". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $1799 ($150 CPU + $1649 GPU). Your GeForce RTX 4090 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 card with a significantly better value rating.
Your GeForce RTX 4090 is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your Rainbow Six Siege performance right now. GPU fully utilized at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
Rainbow Six Siege 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.
Rainbow Six Siege requires at minimum a Core i3-560 (CPU) and GeForce GTX 460 (GPU) with 6 GB RAM and 61 GB storage. For the recommended experience, you need a Core i5-2500K and GeForce GTX 670 with 8 GB RAM. Your Core i7-3960X Extreme Edition and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Rainbow Six Siege 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.
