Hm.... worth it if you intend to shoot professionaly I think. As in, make some money with the pictures you take.
Otherwise, I wouldn't think so. I mean, I take pictures just to print them out at 8x10 or less, or to post online... and for those two purposes, a $3k+ camera is quite over kill.
That's just my opinion though. I'm by no means a pro or anything so take it or leave it.
