Build estimate
Core i5-12400F and RTX 4060 bottleneck estimate
The Core i5-12400F and RTX 4060 are a practical budget-to-midrange combination. They are generally well matched for 1080p gaming, with the exact limiter depending on the game and refresh-rate target.
1080p
Most games should feel balanced. CPU-heavy games can still show a processor limit, but the RTX 4060 is often the more important part for visual settings and demanding newer titles.
1440p
At 1440p, the RTX 4060 becomes the main constraint more often. Use upscaling or tuned settings if you want smoother performance in demanding games.
Upgrade advice
For 1080p, this pair is reasonable. For 1440p or higher settings, a stronger GPU usually brings a larger improvement than replacing the i5-12400F.
