Off topic:Shift to bioinformatics or get postdoc?

Question

[biotech]

I will defend my thesis soon and be PhD in Microbiology. I've been able to publish some papers, with work related to host-pathogen interactions, using bioinformatics tools but working at higher levels, not doing complex programs, rather using them.

I've been accepted in a bioinformatics Master's degree. My question is if does it worth to study this Master's or, instead, skip Master's and continue my career without it. This option would imply to accept a Postdoc offer (probably abroad), but I can only accept postdoc jobs paying more than 2500 $, since this is what my girlfriend is earning as a nurse in Spain.
