Question Please, help me to choose a laptop

Mar 29, 2021
Hello! I'm trying to choose the most suitable variant. I need a laptop for video editing, in DaVinci Resolve (not only for this, of course, but it's the most demanding process). And I want a convertible, a 2-in-1, because it's very comfortable for me.

Now I'm choosing from 3 variants. New Lenovo Flex with Ryzen 7 4700u, used Yoga 720-15ikb (with i7-7700HQ and GeForce GTX 1050) and used Dell XPS 9575 (with i5-8305G and RX Vega M GL). First two have 16 GB RAM and 512 SSD, the last one -- only 8 GB RAM and 128 SSD. Prices are nearly the same. Visually I prefer Flex, I think, and also it has a 14-inch display: it's slightly better for me.

Thank you in advance!
