A degree is just a bit of paper - it wont get you a job. Your skills as an artist will get you the job. The question is how you want to obtain those skills.

I'm going for a (traditional art) degree mainly because i want to build my drawing skills, and i'd rather learn with teachers and others students in the classroom. Plus, as one of the links below note, there is an overwhelming lack of the basic art principals with 3d communities. Understanding basic art fundamentals will give your work a big boost. I would prefer to learn the fundamentals, then adapt them to 3d. Why would you wanna learn to run before you can walk?

Would you have a discipline to teach your self? It may go in your favour if you do, however you wont have real time constraints that you would have in college - there wont be anyone breathing down your neck for completed projects. This can prep your for the real world.

There's many reason for or against a degree - these links note some of them:
