How Much Is It Worth?

My decision to change jobs has brought up a serious question: how much is job satisfaction worth to me?

When my previous office closed, I took about a 6K paycut per year for my current job. Turns out, I took that pay cut to do menial tasks and be unhappy a good portion of the time. Now I have the chance to get into a great, and I mean great, place to work, but if I do I will lose perks that have serious monetary value. If they don't offer me enough to make up the difference, is it worth it to go anyway to be happier? Or will it change our life so much as to make us miserable? If they don't offer me quite a bit more, I will have gone backwards in real earnings two jobs in a row.

Sigh.
