The one with the 8gb 980m is better. More VRAM is always better. And for rendering and CAD, I'd get that one.

For me, it's the SSD I'd care about, because once you experience the speed of SSD, you may not want no-SSD laptop anymore.

Yeah totally agree. My girlfriend's laptop feels so slow starting up and running stuff compared to my desktop. We turn them both on to play a game together and I'm playing before she can get past the damn windows login screen lol
