GAH! I'm pulling my hair out at this point. It IS an AGP afterall, but there (according to wiki) are two types of AGP slots. A 1.5 volt and 3.3 volt. I had a friend look at my mother board today (Intel D865PERL) and he says he thinks my slot is the 1.5 volt and that the card that I got is a 3.3...he thinks the card I need may be hard to find, but I'm nothing if not persistant.
