For detailed Schematics(engineering) go for a Fire GL if you can, the older ones may be slow but they will show the details much better.
Yes, get the biggest, best LCD you can. (High res preferably).
CAD will see a little benefit from GPU aswell these days unless he's using a really really old version.
You should be able to get a quadro in an M series dell. Go with a quadro/fire GL, the driver additions are quite nice.
