Whats a good PC configuration for X-Plane?
Generally speaking, the more money (hardware) you throw at X-Plane the faster it will run and/or the fancier the scenery it can manage. What you get depends greatly on what you can afford. The availability and prices of PC components change daily. Tony Gondola maintains web pages with recommended components for low end and high end PC configurations. Also see the X-Plane system requirements for recommended configurations and links.
