I have a Compaq AMD 475 with an 8 Mg video card(proprietory)which has never allowed enrichmend from 480/640. It is out of warranty. As I have open slots can I bypass the Compaq vidoe and install a proper board in a common slot? If so, what capacity will suffice for non-complex video, i.e., no major graphics or games? Thanks Paul Tietzen, Palm Springs.
