Hey Kingo, myself personally am a fan of AMD. Have been since 1999
Intel has a tendency to be a few more bucks and really, someone who uses their machine for leisure likely wont see a different.
As for the monitors, i've ran Benq wide screen and Viewsonic, i'm not so impressed with the viewsonic
Why are you going with Dell though ? Why not build a generic system from your local small pc shop ?
