Frequently asked questions

Is the SpecPicks PC Builder free?

Yes — it is completely free with no sign-up. Set a budget and a use case and you get a complete, compatible parts list with live Amazon and eBay prices and a shareable link.

How does the PC Builder choose parts?

It assembles a complete build from real, in-stock catalog parts matched to your budget and use case, then checks CPU socket, RAM generation, and PSU wattage so every part is compatible. Prices are pulled from current listings, never fabricated.

Can it build a gaming PC for 1080p, 1440p, or 4K?

Yes. Pick your target resolution and refresh-rate and the builder sizes the GPU and CPU accordingly and shows estimated FPS for popular games from public benchmarks.

Can it build an AI or LLM workstation?

Yes. Choose the local models you want to run (such as Llama, Qwen, or DeepSeek) and the builder sizes GPU VRAM to fit the largest one and estimates tokens-per-second throughput.

Are the prices real and up to date?

Prices come from current Amazon and eBay listings and may vary. The builder never shows an invented price — if a part is not in our catalog yet it links to a live search instead.

Can I share, tweak, or save a build?

Yes. Every build gets a shareable link you can reopen on any device, swap any component in, or save as a new build — no account required.
