You don't need a capture card to dump P2 footage...But you will need it to handle any HD/SDI monitoring out from the computer. You would also need it if you were trying to ingest HDcam into your system through a deck. The Kona 3 card is the way to go for high end HD work. The Kona 3 matched with a 23" cinema display for monitoring HD out of FCP is pretty awesome.
