I own a drafting & design service. I use AutoCAD / Revit / Softplan every day. I have a stable windows desktop PC that is 100% my production machine. I want to get a mac laptop for "after hours" stuff. Web browsing, word, excel, etc... Will rarely be used for AutoCAD or Revit, but I need it to be capable IF the occasion comes up. So, what do I need? I know what AutoCAD for mac has for system requirements, but I want real world opionions (experience prefered). SO, If I were getting a windows laptop I would get a dell xps 15 (2.2ghz 6 core, 16gb, 512gb). I do not know enough about apple to know how resources are used. Do I need comperable windows specs? Does mac os use resources better / worse? I know I will need minimum 512 gb ssd (I use dropbox as a file server and need that size), but what about processor and ram? I have my eye on a 15.4" pro with the 560x ($2499 @ BH Photo - Best Buy price match). Am I throwing money away getting the 2.2/16 system? Will a new i5 8 512 air work for what I need? REQUIREMENTS: 512 GB SSD Fast, I do not want to wait on the computer to do something, I want it to be faster than me. So, with all that said, someone teach / explain / lie about the spec similarities / differences between windows pc and mac. I will be purchasing something tomorrow most likely. Thanks in advance.
