Didn't you answer yourself?
It requires a card other than the one you have, so you will need an
NVIDIA 8 series (8600 min 8800 recommended).
I recommend an 8800gt with 512mb, because they work fine, only use a single slot, and have dropped alot in price lately.
I paid $269 when I bought mine from
TigerDirect (30/10/2007) and now you can pick one up for $179 that includes a game.
Quote: "mobility Radeon "
I know very little about ATI cards, but that mobility thing makes it sound like a laptop card.
Is this for a laptop?
If so then you will need a
M series NVIDIA card.
