So I currently have the base 15 Haswell rMBP. I have initially tried out the higher end model with the discrete graphics but eventually returned it for the base model. Processor wise, I believe that the 2.0 model meets my needs considering I only plan to do light video and photo editing. I dont plan to play games on this unit. But what I noticed, starting up my Win7 session via Vmware already uses the whole 8GB of ram. Im aware that Mavericks may handle RAM differently compared to the previous OSX but I dont want to encounter any problems 2-3 years down the road. Also, I think that I will have better peace of mind with the 512GB SSD not having a need to use an external disk. I probably have 80gb of pictures alone. I would like to create Final Cut, iMovie, iPhoto, etc projects without worrying much about space being consumed. Now that being said, will the extra $600 I have to pay will be worth just having a bigger SSD and 16GB of ram which I am actually after? And having the discrete graphics and processor upgrade included but not really a need for me. Thank you in advance for your opinions and insights.
