BottleneckScore — free PC bottleneck check & upgrade advisor

Pick your CPU and GPU (380+ parts), your usage (esports, 1080p, 1440p, 4K gaming or content creation), your RAM and storage — and get a 0-100 build score, the component actually holding you back, and the upgrade with the best real performance gain per euro, priced from live EU retail offers refreshed weekly.

The engine is deterministic: real benchmark data, usage-weighted, with RAM and storage multipliers — same input, same verdict, no AI guesswork. And when your build is already balanced, it says so: keep your money. Free, no account, no signup. Prices are EU (EUR) for now; US and UK support is coming.
