I have an old HP computer with onboard graphics and want to add a video card to have dual monitors. It is just mainly to expand my work area, not doing anything consuming a lot of resources, so just an inexpensive card will do that supports dual monitors. The AGP port in the system says "1.5v AGP only". Can someone point me into the direction of a card that would work for something like that, or what i need to look for to make sure it is compatible?
