Before you go and buy CC3, you may want to explore what you can do with the software that you already possess and are familiar with. There are allot of loyal CC3 users out there (including some influential members here at the Guild) who love this software and can skillfully employ it to great affect. However I hear that there is a learning curve involved, and while the initial package is cheap, I hear that it is somewhat limited unless you decide to purchase additional software (and the price can quickly add up for doing so). Moreover, as a personal taste, overall I have been far more impressed with the capacities of PS (and GIMP for that matter) than I am with that of CC3 (no offense to you CC3 loyalists out there!). Thus, I'd reccomend trying your hand at some of the tutorials here before making the decision to purchase additional software; you may find that you don't need it after all.
