BottleneckPC

Free bottleneck calculator & PC-building tools for gamers

BottleneckPC is a free suite of PC-building tools. The core bottleneck checker tells you if your CPU and GPU are holding each other back - as an honest range, not a fake-precise percentage - with estimated FPS at 1080p, 1440p, and 4K and concrete upgrade picks at live prices. It also includes a PSU wattage calculator, RAM advisor, case finder, and full pre-built gaming PC recommendations. No signup, no fluff.
