I am not with Laminar Research; just a flight simmer.
The following link at http://www.x-plane.com/kb/x-plane-11-system-requirements/ provides information on the system requirements to run X-Plane. You may have to run the CPU in overclock mode.
If you are satisfied your system meets the recommended requirements download the demo mode from http://www.x-plane.com/desktop/try-it/ and try first. Each time you run the demo it has a time limit of approximately 10 minutes from the time you make your selections and press the run button.
If you chose to purchase X-Plane, the demo mode can be unlocked when you enter the password key which is provided when your order is processed.
Good luck and welcome to X-Plane
