Trouble deciding on upgrade body.

Please excuse me if this isn't the right place to place this thread. I am new to the DP forums and would appreciate any help I could get.

I'm currently looking to give my Canon EOS 60D to my girlfriend and upgrade to a new body. I shoot all kinds of photos primarily landscapes, portraiture and macro. Every so often I shoot sports and do studio type shoots. The cameras I was considering are the Canon EOS 7D, 5D mk ii, and the 1Ds mk iii since I could get the first two new and the latter used for around the same price. Which would be most suited to the kind of photography I do and why? I have considered the 5D mkiii and the 1D mk iv, but they are out of my price range. (I'm sorry if this topic has been beat to death).
