Thanks for the replies
I have no doubt my system will run it.
I also have no doubt its a great game. Unfortunately I just ordered a Trackir which seemed almost essential to me since I am abit challenged by trying to running the hat view while flying at this point. It just made sense that it would make the games more enjoyable ( I hate to lose too lol) I dont have CFS now so I also have to get that ( 3 kids a wife etc.. you know) money is tight for a while and was hoping that I could just download OFF and I would be good for a month till I could swing BHaH. The videos I have seen look great and the sound seems very realistic.
