Hey Product Hunt! 👋 I built BottleneckCalcs because I was tired of seeing people spend money on the wrong hardware upgrade. The problem: most gamers don't know whether their CPU or GPU is the weak link, so they guess, often wrong. A new GPU won't help much if your CPU is already the bottleneck, and vice versa. What BottleneckCalcs does: ⚡ Analyzes CPU + GPU compatibility using real benchmark data (3DMark, Cinebench) 🖥️ Supports 1080p, 1440p, 4K, and 8K resolutions 🎮 Adjusts for workload type (gaming vs. video editing vs. general use) 🧠 Covers 140+ CPUs and GPUs from Intel, AMD, and NVIDIA 📊 Gives bottleneck severity scores + upgrade recommendations 💸 Completely free, no account required The engine normalizes performance scores against reference hardware, applies resolution-specific weighting, and compares the result against an ideal CPU/GPU balance point for each resolution. Whether you're planning a new build or deciding if that RTX 5080 is worth it with your current CPU, this tells you before you buy. Would love your feedback! 🙏
