The 8500 is a low end card and the rest of your system is pretty high end. I would recommend a 8800GT (512MB), 8800GTS (512MB, the 640 version actually uses an older and slower GPU), or 9800GT. I think upgrading the video card will allow you to get the best performance and visual quality from Il2. As for the graphics card GUI, I prefer nHancer as it gives more options for AA and AF modes. nHancer will not allow you to overclock, set fan speed, or check temperature, for those functions you will need other programs.
