Here are my specs Macbook Pro 2.33GHz core duo 2Gb of ram 256 Graphics card Lion 10.7.5 I need to be able to edit 1080p at 60fps from my gopro 3. I've tried it on my laptop, but it's very choppy and dropping frames. An external drive might help a little but I'm concerned that my machine is just to slow to process the data. I would rater not go through with a costly update if possible. Can I make this work or am I too outdated?
