From what I've read AutoCAD favors CPU performance and isn't highly threaded (you want more performance per core and NOT more cores).
As for Adobe products they recommend more cores and workstation type graphics cards. I'm not too familiar with those GPUs but I'm fairly sure their architecture is optimized for work applications and not gaming. And you probably won't have those options on a laptop.
Opinions:
You'll need a solid CPU.
High end graphics aren't critical but I've read that
Photoshop can and will take advantage of it.
You probably don't want to do this but see what your school's computer labs have to offer. If you can do your work better on the school PCs you might as well optimize your PC purchase for gaming. Most laptop hardware just doesn't match up to desktop performance.
