Hi PH! I built Bottleneck Calculators because most bottleneck sites just spit out a percentage with no explanation. This one tells you which part is limiting you, at 1080p/1440p/4K, and what to upgrade first — plus FPS, PSU and RAM calculators, a build comparison tool and a public methodology page showing how the estimates work and where they stop being reliable. It's free and needs no account. Feedback on the pairings you'd like covered next is very welcome.
