The Scotland playmaker completed a £2.5million move to the south coast club from Celtic on deadline day.
Speaking to Cherries' club website, Christie said: "It sounds a bit crazy but I've actually had an affection for Bournemouth for years now.
"Believe it not Bournemouth put a bid in for me back in my Inverness days as a really young player. You could say I've looked out for the club for a good few years now.
"As soon as I heard the club were an option, I managed to speak to Scott Parker and with the way he spoke, he's a big encouragement in terms of the brand of football and the way his teams play.
"From watching what he did with Fulham and then seeing him come to Bournemouth I think I'm taking a big step in the right direction.
"The whole feeling of it was right and even though I did have a couple of other options this was the one that I was just desperate to get over the line."
