Master Degree Vs CCIE

I already got CCNA , MCSE and CNE rencetly. My time and money is limit, and I consider to spend my effort to get either a CCUE or a Master Degree in this few year. Does anyone prefer to go back to school (may be part time) and try to get a Master degree in Inormation technology or work on my certification CCNP, CCIE..?

Thanks for any inputs.
