FS 2004 VERY slow framerates

Hi all,
I hope you can help me here.
I just uninstalled FS2000. I was using an AMD 64 3500+ CPU, Abit AV8 MB, 1 GB RAM, and an nVidia MX400 64 MB card. I was getting over 60 fps with all FS2000 display info at maximum.
Yesterday, I installed an ATI 9600 XT 128 MB card. I also installed FS 2004. Now I'm lucky to see 20 fps with everything set a minimum, and it drops to about 1 fps on the ground at even the most desolate fields! I can't figure it out!!!! Did I just waste $250 for the video card? I have ALL the latest drivers for the hardware and the patch of Flight Sim installed. Even did a BIOS update, and have the newest DirectX version. What am I doing wrong? PLEASE HELP! ???
Thanks in advance!
