Okay, I'm getting the 2017 macbook pro. 15 in. My first laptop, but many imacs and previous iterations of apple computers. I'm clear on all but processor speed. Currently jealous of the new imacs that are out now, but I have a need to be portable. I use lightroom and photoshop intensively for personal use. When working from home I can use photoshop, illustrator, indesign, acrobat, several browsers, powerpoint and word all in the same day easily. 16gb of ram is limiting but I can deal. No motion or 3d. I will have a high end monitor attached most of the time, but I'm assuming the 4gb card is fine. I hear reports of the heat created from the higher end processors. I'm probably asking a dumb question, but is it safer to go with a slower processor or better to get the most I can afford? For long term durability and/or less problems does it make a difference?
