It is a GeForce 7300 GS.
Didn't think it was relevant, thought it was more of a general question if it would be possible to run a stripped down gnome3 or perhaps even another desktop environment on the other card while still running the full gnome3 on my good card and main screens.
But I guess I should have added it, never hurts to have more info
Also, just to make it clear, The card is too old (or at least I assume that is the reason) to run the fancy new gnome3 features. I can use it in fallback mode or with other desktop environments like xfce.
thx for the reply
