Show HN: Most GPU Upgrades Aren't Worth It, I Built a Calculator to Prove It

I run a small project called best-gpu.com, a site that ranks GPUs by price-to-performance. While browsing PC building forums and Reddit, I kept seeing the same question: “What should I upgrade to from my current GPU?” Most answers are just lists of cards without showing the actual performance gain, so people often end up paying for upgrades that barely improve performance. So I built a small tool: a GPU Upgrade Calculator. You enter your current GPU and it shows: estimated performance gain a value score based on price vs performance a filtered list of upgrade options (brand, price, VRAM, etc.) The goal is simply to help people avoid spending money on upgrades that aren’t really worth it. Curious to hear feedback from HN on the approach, data sources, or features that would make something like this more useful. https://best-gpu.com/upgrade.php https://best-gpu.com/upgrade.php
