I have used G2, G3 and AFPD and to me there is nothing that compares to AFPD. It is about a realistic as it gets. G3 is pretty good too, but I do not think that it feels as real as a well setup plane in AFPD. www.aeroflypro.com . Your computer will run it with that setup. I had a 9600 and it worked fine.

Also, someone mentioned battery consumption. Pull the frequency module out of your transmitter and the batteries will last a VERY long time. I can go weeks without needing to charge on a 1500mah NIMH battery.
