I brought the computer in Israel - the card is pretty standard for Gamer PC. As for now it worked fine with any game my son tried to run on it and perfectly with realFlight. As indicated by some on other discussion treads any of the three main player should work fine on your machine (a bit of overkill if anything) reflex and Aerofly are said to be better for 3d model simulation. I do not feel I qualify to judge
