You're upgrading from a II, right? I think the more apt question is whether the upgrade is worth it.

I'm hearing that the Mark III has issues with focus that were not present on the II model. I'm also hearing that the improvement in image quality is marginal. I've also actually heard tales of woe regarding the more novel of the new features: micro adjustment and anti-dust. I've heard more than one user of the III say that he has issues with lenses on the III that he/she never had with the II. Apparently you have to microadjust on the III to get the same quality that you had with no microadjusting on the II.

All in all, the upgrade sounds like a headache I can most certainly do without.
