Yea you can have 2 graphics cards in a machine....

The old games that you refer to though, wont have the capabilities to switch to a second graphics card...

The primary and secondary display that you refer to, is having 2 monitors (or monitor and TV ) on 1 graphics card... (mostly NVIDIA that gives you the menu options for that)

I know WinXP has capabilities of having 2 display cards and having certain programs run on each one....

I have no experience with ME doing that though.... there should be 3rd party software available to run 2 graphics cards on ME and set programs to run on specific ones.

I am sure that once you install 2 cards, your display control panel will adapt and give you the extra options you want...

Yea it can be done.... as to how... hmmmmmmmmmmmmmmmmmm

Your existence alone, is excuse enough for the creation of the entire universe… Il you my darling Jeanne-Dré 
