I need to add a video adapter to a Dell Optiplex 7020.  I looked at the specs, and there is an option to install either a PCI Express x16  or  an x4.

All that the user (Stuart) is doing is word processing, excel, business applications.  No gaming.

Which card should he get?

x16 cards are more common and probably less expensive. So get an x16 card. x4 cards I'm not even sure they exist. Besides that you can use x1 cards and above in the x16 slot. So basically it doesn't really matter, you can also get an x1 card and it will work. Those I know exist (but they are still less common than the x16 cards).

A PCI Express x16 card will give you the most grunt and flexibility for your machine and leaves the PCI Express x4 possibly available for other uses.

Can't see why you can't use the onboard graphics for the tasks you are proposing.

I didn't mention that the user wanted 3 monitors.  The Dell has 2 built in which are in use.

An x16 card definitely then.

Possibly a nvidia quadro nvs510.  That will support 4 displays.
