DC1- Real Flight is by far the best and I have tried them all. You should have no problem using the highest resolutions with the computer you mentioned. I am using basically the same system but with the 1 gig t-bird. Make sure you also download the latest drivers for your video card. Another cool thing about the GeForce MX 2 is you can overclock it making it even better. You have to download a program called "cool bits" to unlock the overclocking screen in the advanced menu. My overclocked MX benched 40% better than stock. Also make sure you are using 4X AGP and fastwrite enabled.
The best thing to do to check your systems game playing capability it to go to http://gamershq.madonion.com/download/?3dmark2000.shtml
and download the 3dmark2000 benchmark program and see how well your system performs. My benchmark was 5865 for reference. Cool program!
