How PCFinder works
Optimized allocation
A greedy optimizer spends every dollar where it buys the most real-world performance — GPU-first for gaming, cores-first for creation — enforcing socket, memory, PSU-wattage and cooler compatibility at every step.
Live seller checks
A Cloudflare Function scrapes sellers in your region in real time (cached 20 min) — Amazon, Newegg and eBay in the US; Amazon UK, Overclockers UK, AWD-IT and eBay UK in Britain — filtering out prebuilts, bundles and accessories. Sources that block automation fall back to estimates and one-click deep links to Scan, eBuyer, Best Buy, Walmart, CeX and more.
Used market, done right
Optional eBay used-part search is locked to New / Open-Box / Certified-Refurb / Pre-Owned from sellers with strong feedback, bans broken/"for parts"/mining listings, and pulls the full condition write-up, seller stats, returns window and item specifics for the top pick.
