I can't say definitively as I haven't done any kind of "split-test analysis", and clearly there's a lot of selection bias in that I tend to speak only with recruiters who like my CV. Also, when going for a specific job, I edit it to prioritise the relevant bits.

For the type of jobs I want, in London, I do need a good CV. I also need a StackOverflow profile, industry connections (which I tend to make through meetups and conferences) and a portfolio. I should really have a blog as well. But I'm simply too small a fish in too big a pool to get by without a good CV.
