Hey guys I am new to this whole HD thing and had a few questions before I drop some serious cash on an HVX200a. I was wondering what the min requirements would be to be able to edit HD smoothly. I am currently using a MacBook Pro with 2.53 GHZ Intel Core 2 Duo, 4 gb of ram. It only has 230 GB of HD space. Some of have told me that the main thing for HD is having fast HDs I would buy an external HD anyways but I feel like I am missing something. I also have a 20 inch Dell monitor that I plan on using for long editing sessions. If someone could elaborate that would be great. Thanks.
