Review on Old Model: Canon EOS 5D Mark II Full Frame DSLR Camera (Body Only) - Review, Specifications, and Pricing by Wiktor Stpie ᠌

the shutter noise is much lower, at 16000, but not worth it moreover, except maybe because of the speed of shooting. if you, like me, are actively involved in photography and have a third mark or choose between 3 and 4, I recommend waiting for the release of the fifth. the additional megapixels are not particularly important (there are only 8 more of them).
