I have a Dell XPS with a Quad Core and 4 gig of ram.

I use a Panasonic AG-DVC 30 3CCD cam and I capture my video with a IEEE 1394 firewire......into Pinnacle Studio Plus (Editting Software)

Just so you know...5 years ago I was making 30 minutes DVD with an old Dell and Celeron process with 30 GIG....not recommended but its capable....
