The only piece of advice I can give on this is that having entered the tech industry at the end of the desktop revolution and the dawn of the web. I left school for the money that was flowing, it was a smart move, but my regret was years later when I returned to school I naturally went right back into a technology based track. In hindsight I wish I would have went back Applied Mathematics, EE, ME, hell even Accounting something that would have broadened my horizons. There is no doubt that I learned a thing or two in CS, but I was already well entrenched in my career, it did not help me in the slightest from a career advancement prospective. It would have been time better spent broadening my horizons in a complementary study.
Depends what you plan on doing. Also all that knowledge is available for free. Guess it depends what you think the piece of paper is worth.
