League of Legends
As the world's most popular MOBA, League of Legends runs on a proprietary engine that has been updated for over a decade. Recently, Riot increased the minimum requirements to include AVX instruction support and dropped support for older OSs and DirectX 9. While still lightweight, modern team fights with complex particle effects can strain older integrated graphics. The game scales well with single-thread CPU performance, meaning even modern entry-level processors can deliver high frame rates.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 593 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 400 FPS. At 4K, all settings exceed 248 FPS.
The GeForce RTX 5090 is 1304% above the recommended GPU (GeForce GTX 560) for League of Legends. The M3 Max 14-Core is 470% above the recommended CPU (Core i5-3330).
No major FPS-ceiling mismatch detected. The GeForce RTX 5090 and M3 Max 14-Core stay close in effective frame-generation ceiling across the tested resolutions and quality settings.
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 Ultra, where the GeForce RTX 5090 reaches about 560 FPS, while the M3 Max 14-Core still has headroom up to roughly 593 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 3 out of 12 cases, CPU-limited in 0, and balanced in 9.
Overall, this is a balanced combination in this game.
Neither the M3 Max 14-Core nor the GeForce RTX 5090 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 M3 Max 14-Core with GeForce RTX 5090, our current GPU anchor. To estimate the GPU ceiling, we pair the GeForce RTX 5090 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 M3 Max 14-Core paired with the GeForce RTX 5090 can run League of Legends smoothly up to 4k achieving around 248 FPS at Ultra quality. Your GPU is 1304% above the recommended specs, and your CPU is 470% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced - this ensures you're not overspending on one component that the other can't keep up with.
This setup is already well-balanced for League of Legends. In the Performance Limiter Analysis, neither side consistently defines the maximum FPS across the tested presets. Across all tested settings, the distribution is 3/12 GPU-limited, 0/12 CPU-limited, and 9/12 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.
League of Legends 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.
League of Legends requires at minimum a Core i3-530 (CPU) and GeForce 9600 GT (GPU) with 2 GB RAM and 16 GB storage. For the recommended experience, you need a Core i5-3330 and GeForce GTX 560 with 4 GB RAM. Your M3 Max 14-Core and GeForce RTX 5090 both exceed the recommended specs, so you're well-positioned for a great experience.
These League of Legends 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.
