Hi,
I think, and that’s just me, but integrated video is fine for NLE, the shared video RAM mean that it will use a portion of the system RAM, the 512MB, for video RAM, typically today, by default they’ll set that amount aside for video to 32MB, but it can be modified through the BIOS very easy, you can for instance decide to put it down to 16MB, or up to 64MB.
Have an ice day 😉
