try to make this story short, im now using my 32" samsung lcd hdtv for my monitor on my powermac g4 digital audio. i have read articles on video cards and i think what i have is a NVIDIA GeForce2 MX Graphics Card. right now the picture looks great but everything could be better. i figured that my computer is old, believe 1999, therefore i might be able to upgrade the card. is this something i should spend the money on or just leave it as is ?
