When you buy Aperture from the App Store you can install it on all the Apple systems you own so if you buy it now you will be able to install it on the iMac when you get it for no additional charge.
This will give you two months or so to get use to the program, play around with it and learn it. Aperture is a great program but does require some time to get up to speed on it. Even if the performance isn;t great on your current set up (and I have no direct knowledge of this one way or the other) the time you spend with Aperture now will not go to waste..

Get it now -- as Frank says, it takes a while to learn to use it, and even longer to use it well.
Performance shouldn't be an issue.. I upgraded from a 13" 2.26 GHz machine w. 8 GB RAM -- ran Aperture all day long. (The retina display and the SSD drove me to upgrade.)
