Low Budget Engineering School Laptop

I'm currently helping a friend find a ~$600 laptop that will run engineering programs such as AutoCAD and Solidworks decently. I am having trouble deciding between several laptops at the moment. Would it make more sense to get a machine with an i7 dual core processor with no dedicated gpu like this Hp 15t or a dual core i5 with a weak dedicated gpu machine like the [Acer E15](https://www.amazon.com/Acer-Aspire-E5-575G-53VG-15-6-Inch-Windows/dp/B01LD4MGY4? SubscriptionId=AKIAJQYFXGBZ6MDO67HQ) that has a 940mx and the Lenovo Ideapad 700 with a slightly better gpu, the gtx 950m? Any advice or better suggestions would be greatly appreciated.
