PCPartPicker provides computer part selection and compatibility guidance for do-it-yourself PC builders. PCPartPicker aims to answer the following questions: - Which parts give the best performance for the price? - Which parts are compatible? - How do prices compare across merchants? Using PCPartPicker, you can assemble a part list representing your desired system, including choice of CPU, motherboard, RAM, hard drives, case, power supply, and other details. Part lists can be permanently linked to, so that it may be easily shared with friends for comparison or discussion.
