Performance Report
At 1080p, all quality settings exceed 378 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 296 FPS. At 4K, all settings exceed 215 FPS.
The GeForce RTX 4090 is 1051% above the recommended GPU (GeForce GTX 750) for Garry's Mod. The Xeon W-3175X is 249% above the recommended CPU (Core i5).
At lower resolutions (1080p ultra, all 1440p settings, all 4k settings), the Xeon W-3175X sets the FPS ceiling. As graphical load increases at (1080p low), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p (medium/high).
Approximated average price on current market:
Combo price: $4648. At 1080p Ultra, this combo delivers 378 FPS, equivalent to 0.08 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k high, the Xeon W-3175X sets the ceiling at about 266 FPS, while the GeForce RTX 4090 could reach 391 FPS. In this scenario, the CPU limits the GPU potential by 32% (FPS gap: 125 FPS). Overall distribution: CPU limits 9/12 cells, GPU limits 1/12, balanced 2/12.
Your Xeon W-3175X is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 10% | Balanced | Balanced | CPU Limits GPU 11% |
| 1440p (2K QHD) | CPU Limits GPU 18% | CPU Limits GPU 25% | CPU Limits GPU 28% | CPU Limits GPU 31% |
| 4K (Ultra HD) | CPU Limits GPU 23% | CPU Limits GPU 28% | CPU Limits GPU 32% | CPU Limits GPU 32% |
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 Xeon W-3175X + GeForce RTX 4090 pairing runs this title with CPU utilization between 19% and 32% and GPU utilization between 3% and 15%. Xeon W-3175X keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 9% at 1080p to 9% at 4K, while CPU averages move from 30% to 24%.
Neither component is close to saturation: CPU tops out at 32% and GPU at 15%. This pattern suggests possible engine-side limits, an FPS cap, or workload constraints unrelated to raw hardware throughput. It also shows why low utilization does not automatically mean there is no FPS limiter.
At 1080p, averages sit around CPU 30% and GPU 9%. At 1440p, that shifts to CPU 24% and GPU 9%, and at 4K it reaches CPU 24% and GPU 9%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
1080p (Full HD) Low is the most balanced preset based on this dataset. It runs around CPU 30% (27-32%) and GPU 9% (3-15%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Xeon W-3175X remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Xeon W-3175X and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the Xeon W-3175X paired with the GeForce RTX 4090 can run Garry's Mod smoothly up to 4k achieving around 215 FPS at Ultra quality. Your GPU is 1051% above the recommended specs, and your CPU is 249% above the recommended requirements.
This CPU + GPU combo costs approximately $4648 ($2999 CPU (Rank #410 Value) + $1649 GPU (Rank #77 Value)). Your Xeon W-3175X 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 EPYC 4585PX is a great upgrade option for around $699 (Rank #66 for value) while costing less than your current CPU.
Your Xeon W-3175X 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 Garry's Mod performance right now. CPU fully utilized at: 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra. GPU fully utilized at: 1080p low.
Garry's Mod 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.
Garry's Mod requires at minimum a Pentium 4 (CPU) and GeForce 6 series (GPU) with 4 GB RAM and 5 GB storage. For the recommended experience, you need a Core i5 and GeForce GTX 750 with 8 GB RAM. Your Xeon W-3175X and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Garry's Mod 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.
