Most students will look at laptops, and should be aiming for at least 16GB of RAM and 250GB of hard-drive space. That said, you should maximize those as your budget allows (buy the biggest HD/most RAM you can afford). Additionally, it’s a good idea to plan on some extra money for a backup hard-drive (1TB or larger), an adapter to use the monitors in our labs (https://www.apple.com/shop/product/MMEL2AM/A/thunderbolt-3-usb-c-to-thunderbolt-2-adapter), and maybe a large monitor for dorm/home.
As for software, the main tools we use here are the Adobe Creative Cloud suite (https://www.adobe.com/creativecloud/buy/students.html) which runs $30/month for access to all of Adobe’s products. The other tool we use a lot is Sketch (https://www.sketch.com/), which runs $99/year, but does offer a 50% discount for students (https://www.sketch.com/store/edu/).
