I'm looking for a laptop to take to college. It will be used for school work, multimedia purposes, and light/medium gaming. Preferably it would be thin. I've been looking at gaming laptops like the msi GS70 stealth and non-gaming laptop like the Dell xps 13. There are two main problems I'm having. The first is that many laptops that support gaming have garbage battery life so I'm trying to find a decent balance. The second is that I'm still trying to figure out if a 3k res laptop is worth it. I know scaling can be a problem but how big of a problem actually is it? I've read threads saying it's the end of the world and some threads saying it's irrelevant. Also, my budget is around $1,500 but as shown by my searches, I can go a bit higher.
