If you can get both for a similar price, I think this is a better option, for BG3 8GB of VRAM will be more than enough, and in graphic power with both you will be fine, the two CPUs will not have any problem either. Also, the laptop with the 3080 I see has the FHD (1080p) screen, I don't see the point of that GPU with a screen like that.
