Hey, Vesie! How about a personal anecdote? Last year about this same time of year, I changed my camera from an entry-level D5000 to the very capable D7100. I had several reasons for the change, one of which was the screw drive autofocus. I wanted to be able to use some of the older lenses that can be had very affordably, but the D5000 cannot focus them. There were other factors involved as well, such as the magnesium chassis, dual card slots, Nikon CLS commander mode, auto focus fine tuning, etc. Since some folks on here nix the upgrade for pragmatic concerns, but I will add this: When you invest money and make the commitment to upgrade, you get a "shot in the arm" kind of morale boost, and find yourself motivated to learn more and do more. This is over and above the practical considerations of "is your current camera good enough?" I say go for the upgrade, as long as you can afford it. Oh, and have fun with it!
