Like I think I said earlier, there really is not a good computer yet to run CFS3. That program is ahead of it's time. At least that has been the talk that I have heard on the message boards and for that reason I did not purchase it. I can tell you that I believe to have any success at all with CFS3 you will need a 128 mb ge-force 4 video card. Unfortunately they are very steap in the wallet right now. Talking between 300-400 dollars just for the video card. System looks pretty good but I am an athlon processor fan rather than intel. It will run Realflight with no problems. Good luck.
