Both my comment and Mr.Scott's comment were deleted (before I had a chance to read his comment, except the email notification that he replied to this thread) so I guess you don't believe me but better reviving an old thread with correct information than letting it be, it belonged to a HP PavilionElite HPE-345sc which also was found in the trash, attached is a photo of the graphics card.
PS
Getting older I become more and more interested in retro computers so this card is not irrelevant to me, especially since it has such a huge amount of graphics memory for the time, below the graphics card is my 8800 GTS 512 which this card trumps, it even tumps the 8800 GTX with a big margin and more than double the graphics memory, it was a huge jump for nVidia.
