I had assumed that Google ignores everything beyond what it shows on the SERPs. I checked one page listed for my site, and Google cut of after 62 characters. Thus, either 62 or a few characters more. Google may index more than this; I dunno. However, I presume the more words in the title, the more the value of each is diluted. Thus, unless youve absolutely gotta I'd say stay to 62 characters.
