I have purchased quite a few high end computers--my last being an Alienware Extreme Edition. I thought that was very fast, but when Greg and Ken configured a Jetline System for me I was incredibly surprised. The load times for FSX on my Alienware was 8-9 minutes including REX. The load time on my Jetline is about 36 seconds. The only words I can use to describe the quailty of the computer is a masterpiece of fine art. If you want a computer that will run FSX the way it should be, call Jetline now and don't look back..
