I am looking to buy a new laptop this summer. Primarily, this is for school use and must be decently portable and have good battery life to last me the day. But, I also do video editing as a hobby, and I am trying to decide whether I need a discrete GPU. They eat power, take up space and the laptops that have them are all gaming oriented and VERY expensive. The question is, do I really need dedicated graphics, or is the iGPU on the processor going to be okay for video editing and other content creation.
