I am getting pretty deep into using Motion 5 and After Effects and my 2011 MBP 13" is not able to keep up. It actually lags pretty bad. What would you recommend for a machine to handle this? I am really open to anything. Just over this lagging. Would be willing to get a desktop and just keep the laptop for small edits and the like or could upgrade my laptop if the others will work better. I have been looking at the 15 or 17 inch MBP's but I am not sure if they will even be great for all of that video creating / editing because they are still laptops. What would you recommend? Thanks for your help!
