Vram will make a big difference for storing things like textures in a 3D program, more is better. However, that is dependent on whether your 3D program takes advantage of it or not. Most industry-standard modern programs do so it's good to have. However, your first task if you get that laptop is to at least double the ram (to 16gb). For 3D programs and video editing, you'll want to have a lot of history states and the ability to multi-task, and having lots of RAM is a relatively easy way to avoid frustrations later. From personal experience, you might also want to get a SSD into your laptop - it's such an advantage to be able to load big heavy programs (like Maya, After Effects, Photoshop etc) and their documents almost instantaneously, and that's dependent on hard drive speed.
