First of all, I've had several computers to run FSX but none have even come close to my new Gravity GT2 from Jetline Systems! Greg and Ken are true professionals and have helped me several times in setting up my specific needs. They reflect the true professionalism of Jetline Systems. If anyone wants the best computer to run FSX or P3D, they have the best in the industry bar none!!! I appreciate their willingness to help me! Thanks again Ken and Greg! You truly are professional!!!!
