Depends somewhat on where (geographically) you want to go, what kind of job you want, and what other portfolio you think you might build up. More prestigious schools do provide a bump, partly due to the actual name, and partly just due to better networking opportunities with things like recruiters showing up to their job/internship fairs. But if you get a good internship and do well in it, that's often more important than where you got your degree.

As for geography, for California specifically, some of the CSUs are actually better regarded than the UCs for some kinds of programming positions: Cal Poly in particular has a reputation for graduating strong programmers familiar with standard software engineering practices, which isn't usually the goal of more academic-CS focused UC departments, and their grads are popular with some employers (especially larger ones). Outside of California, the UC name recognition is probably a bigger factor, though.
