I have the Inspiron 9300 1.73 Ghz 1GB Ram 80 GB HD. I upgraded the video card to the NVIDIA GO GeForce 6800. I am happy with the results.
I think there are 2 monitors to choose from: WXGA+ (1440 x 900) or UltraSharpTM WUXGA with TrueLifeTM (1920 x 1200).
I have the WXGA. I looked at the Ultra sharp but the screen was too glossy for me and reflected every light in the room. Still a super nice screen though.
