So I have been looking into a computer and been trying to choose between a Mac and a PC. For the Mac I will probably not get 16 gb ram but for the PC, I am waiting for a sale to get 16gb ram for the XPS 15. However I am not sure if I really need it and should I just go ahead and get(plan to get) the 8gb version. I search the web, watch videos, play games, and I am planning on doing a little bit of editing some videos(nothing too big though). For games I normally play games that need less than 8 gb and I don't play any of the new intensive games like Overwatch or GTA V. I am 17 years old, and for the most part should the 8gb last me for about 4-5 years inorder to finish 4 years college.
