My review of job postings for PM positions shows that many positions now require a PMP certification and many more note that it's "preferred" (i.e., not required but the employer desires it). This wasn't the case years ago, but times have definitely changed. This is largely what prompted me to pursue getting my PMP certification. Unless you are facing some impediment that is forcing you to go the CAPM route, I would definitely encourage you to work towards a PMP, instead.
Good luck to you!
