I'm using a Falcon NW built Athlon 4800 dual core computer with XP OS and FS9. An ATI 1800 XP 512 Radeon card driving a Matrox 3Head2Go splitter & 3 - 19" LCD monitors windscreen view plus the 24" LCD main panel below. Goflight modules for hard instruments and CH Pro yoke and pedals. It is all mounted on a "out of business" retail store adjustable display rack. The entire set up is very flexible & immersive allowing for easy add-ons and changes. It is a work in progress!
