A developer built a PC Bottleneck Calculator to demystify a common but misunderstood concept in PC performance. The tool helps users understand if their CPU and GPU are well-matched before spending money on upgrades. It addresses the confusion found in online forums where opinions and benchmark screenshots often conflict.

The calculator assigns performance scores to components and calculates a bottleneck percentage. A result below 10% indicates a well-balanced system, while over 25% suggests a noticeable limitation. The goal is to provide clear, real-world insights so builders can avoid unbalanced systems that waste money and underperform.

Building the tool required normalizing wildly varying benchmark data and explaining results clearly, especially for older hardware. The key takeaway is that balanced systems often outperform expensive, mismatched builds. For anyone planning an upgrade, checking component balance first can save time, money, and frustration.
