I have been using an 07 Macbook pro 17inch 500Gb HD for video editing and it is time to upgrade. I am trying to decide between an iMac 27 inch, 3.4 Ghz, quad i7, AMD Radeon HD 6970M 2GB GDDR5, ( will add my own RAM) or new 17inch macbook pro i7. Video editing is my main choice of poison here. Yes, I travel to our cabin often and like to hunker down and edit up there- but I am at a place where I would like to get better at my craft, not worry about hard space, and want it to be quick enough so I can articulate my thoughts better. When I wait around for rendering, I lose my ideas, so something that is quicker will allow me to articulate ideas on the cuff easier. (or so I am hoping) So Portability is cool, but if the iMac will allow me much more horsepower I am willing to forego the portability aspect, as I really would like performance. and no I can not afford a Mac Pro right now. - If the new Macbook Pro i7 core would suffice and hold it's own up to the iMac as then great! portability and peformance all in one, I will go for it. Or am I limiting myself to what and where the imac will take an amateur like myself to the next level of video editing. I shoot with a Canon 7D and I am aiming for a film festival entry. That is my goal. I am currently using an older version of FCE. Any suggestions would be much appreciated. Basically, I am willing to forego portability and do the imac if it will help me reach my goal. If there is not too big of difference, then Macbook pro it is..
