Hi, I recently built a hackintosh and was looking for a photo editing program. I first looked at photoshop but stumbled upon a copy of Aperture 2 for $20. So my question is, for an ameteur, would aperture 2 be worth it or would it be unwise not to just step up to Aperture 3. The only reason I ask is that I don't know if there are major updates to 3 that I would be missing, or absolutely need, that would justify another $60 spent on Aperture 3. Thanks for any responses.
