Hi Guys! I've saved up enough money to go ahead and purchase a Macbook. I'm buying one firstly to use as a laptop and second, to edit videos. I don't see myself editing videos longer than 10-20 minutes on it. For that, I have a personal PC at home that I can customize and upgrade further to handle the heavy stuff. My conundrum lies in which Macbook to get. I'm looking between the two 15" models. You can check them out for yourself here for reference. My question is - would the difference between the processors - 2.2 GHz and 2.4 GHz (both quad core) - make a difference? Likewise, would the AMD Radeon graphics card sporting 512 MB of memory be that much of a difference from the one lauding 1 GB? Video editing capability plays a heavy part in this decision. I'm already strapping it with 8 GB of RAM as well. Thanks for the help!
