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 356 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 356 FPS. At 4K, all settings exceed 318 FPS.
The GeForce RTX 5090 is 1304% above the recommended GPU (GeForce GTX 560) for League of Legends. The Core i5-10600K is 122% above the recommended CPU (Core i5-3330).
The Core i5-10600K sets the FPS ceiling at all 1080p settings, all 1440p settings, 4k (low/medium/high), while the GeForce RTX 5090 still has headroom. The FPS ceiling is closely matched at 4k ultra.
Approximated average price on current market:
Combo price: $2879. At 1080p Ultra, this combo delivers 356 FPS, equivalent to 0.12 FPS per dollar.

This chart answers a simple question: which upgrade is more likely to increase FPS first? In this case, the answer is the CPU.
The largest gap appears at 1080p Low, where the Core i5-10600K reaches about 356 FPS, while the GeForce RTX 5090 still has headroom up to roughly 893 FPS.
That means the Core i5-10600K is hitting its performance ceiling first, leaving a 60% gap versus the GeForce RTX 5090's available headroom in the most unbalanced scenario. Across all tested settings, this pairing is CPU-limited in 11 out of 12 cases, with 0 GPU-limited and 1 balanced results.
Overall, this is a CPU-limited combination in this game.
The Core i5-10600K is usually the limiting part in this game, so upgrading the CPU is more likely to deliver a larger FPS gain than upgrading the GPU.
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 Core i5-10600K 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.
See how your processor and graphics card compare against the game official minimum and recommended system specs. The placement of your hardware is calculated using relative synthetic performance scores to help you gauge overall playability.
Your CPU is 122% above and your GPU is 1304% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

Yes, the Core i5-10600K paired with the GeForce RTX 5090 can run League of Legends smoothly up to 4k achieving around 318 FPS at Ultra quality. Your GPU is 1304% above the recommended specs, and your CPU is 122% above the recommended requirements.
This CPU + GPU combo costs approximately $2,879 ($179 CPU + $2,700 GPU). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #4 for value).
For League of Legends, upgrading the CPU would usually improve performance first. In the Performance Limiter Analysis, the Core i5-10600K is the side that most often caps the frame rate, while the GeForce RTX 5090 still has additional headroom in the tested presets. The main bottleneck appears on the CPU side. The largest gap shows up at 1080p Low, where the CPU reaches about 356 FPS while the GPU still has headroom up to roughly 893 FPS. Across all tested settings, the distribution is 0/12 GPU-limited, 11/12 CPU-limited, and 1/12 balanced.
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 Core i5-10600K 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.
