education - Masters degree in 3d graphics/animation or not?

Next year i will graduate a Computer Science bachelor degree(maybe in the best university of Russia). I have some skills in 3d computer graphics, 3d animation, computer vision. And now i want to know, what should I do, if I want to have a job in a big company like Pixar, Weta Digital or DreamWorks? I am not familiar with USA universities, but I would like you to advice me some good graduate programs(and the approximate price for all years of the program). Or maybe is it not enough to get a good job? Or maybe should I better work these several years? What is the best way?

Sorry if my question is not appropriate for this section of stackexchange.

I would be grateful for any advices!
