I am having to go from a desktop to a macbook pro as I am moving to Japan. Basically I need to do some simple video editing, about 2-3 hours of video each week in Adobe Premiere and export to 2 formats which I have presets for. My question is, will I get a lot of extra kick with 1GB 650m vs the 512MB 650? I just don't want to spend the extra $$ if I don't need to since I will be upgrading the hard drive to a 7200rpm one anyways. Also how would this hurt gaming? I have a decent Steam library (Far Cry 3, hopefully the new Bioshock, Saints Row 3), but plan on getting a PS4 so it is not a deal breaker. Edit: also I am guessing I should stay away from the rMBPs still? Seems to be issues with them from the screen to the heat.
