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.

Frequently Asked Questions
2Is there a more cost-effective setup to run League of Legends?
This CPU + GPU combo costs approximately $1688 ($39 CPU + $1649 GPU). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
3Which component should I upgrade first to improve League of Legends performance?
This setup is already well-balanced for League of Legends. No significant bottleneck - CPU and GPU are well matched across all settings. Both the Xeon E3-1240 and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
4Does this setup support Frame Generation for League of Legends?
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.
5What are the minimum and recommended specs for League of Legends?
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 setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
6How accurate are these League of Legends FPS estimates for the Xeon E3-1240 and GeForce RTX 4090?
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.
