So i will be starting a masters program in geography this fall and was wondering if any of you use you rMBP to run ArcGIS. I was planning on getting the one with 16gb ram and 768gb ssd. would probably split it up 512/256. Any of you running into any issues with graphics performance, etc? I dualbooted via bootcamp for a short while on my current laptop, and it worked fine. This was arcgis 9.3.1 and the screen is 1440 by 900. Still might invest in a second screen. What are your current setups? I am hoping to get a good 5 years out of this machine. One I have now(in sig) has lasted me 5 years and four months.
