A gaming PC builder that does the hard part for you

Most PC builders hand you an empty parts list and leave the research to you. MaxMyBuild works the other way around. Enter a budget, pick a few optional preferences, and it returns a complete, fully compatible build — every part chosen to squeeze the most gaming performance out of your money. Whether you want a tight budget PC build or a higher-end custom rig, the tool weighs three things at once so you don't have to: live prices, real benchmark data, and full compatibility. Not sure what to spend? Start with how to set your gaming PC budget.

Every Build Is Optimized for Three Things

The best price for the performanceComponent prices are refreshed from real retailers at least every 24 hours, so each pick reflects what parts actually cost today. The tool spends your budget where it moves gaming performance most — no upsells, no padded margins.

Benchmark-backed part choicesCPUs and GPUs are ranked by real benchmark scores, not spec-sheet marketing. You get the strongest performance-per-dollar at your budget and resolution.See the GPU and CPU benchmarks →

Guaranteed compatibilityA built-in compatibility checker validates CPU socket, motherboard support, RAM type and speed, GPU clearance, cooler height, and PSU wattage on every build. If parts won't work together, they're never recommended.The compatibility checks that matter →
