You didn't say enough about what you shoot to be able to weigh the pros and cons well. Are you going to print very large? Are you going to shoot in low light? Do you need very shallow DOF? If not, you aren't going to notice much of a difference between crop and FF. If you are displaying on the web and not shooting in low light, you won't see any difference at all because the resolution of the display is so low.
Unless you are shooting wide open, the DOF issue is a red herring. for the same field of view, crops have deeper depth of field at a given aperture. You want shallower DOF with a crop, just open up more. Likewise, if you want deeper DOF and you have a FF, just shut the aperture down a bit. I forget the amount, but it is roughly a stop or a stop and a half, I think. FF is superior if you want very shallow DOF, but otherwise, you can control it to compensate.
The tradeoff in this case is you loose the better AF. If that is important to you, it would be a bad trade.
My suggestion, as someone who has both formats, is to forget about it and go enjoy the very good camera you just bought.
