So, Im getting into making videos and decided to grab one of the new MBAs. As awesome as they are, they are not that powerful and Im seeing long times for transcodes (2 hours iMovie, 35 min Premier Pro). I looked around and saw that I should get a laptop with a dedicated GPU if I want to get an all around better experience. I see someone on Craigslist that wants to trade a well kept 2011 cMBP 15 with the 6750m and 8gb. I have the baseline new 13 MBA. Should I trade? PS: Open to other deals if you know of any. Got the laptop at Best Buy yesterday and still have 59 days to return (Rewardzone Platinum).
