If your interest is limited to factoring Mersenne numbers, then the practical advice is probably: never. Unless you represent a small government or large research collaboration? Only they have the resources needed to approach the smallest unfactored Mersenne number by NFS.

If you are asking in general then Batalov and VBCurtis have good advice.
