Ok I recently got Photoshop CS5 Extended for 10 bucks from some guy who sells stolen electronics and software (he doesn't steal them from the internet, but literally steals the copies from shops).

Ok that wasn't relevant.

Anyway as it turns out (should have seen it coming) Photoshop CS5 is a very complex tool. Too complex in fact. About 90% of the stuff in it I'm sure I DON'T need. At the moment I only need it for drawing tilesets (duh) and some other textures for games (like Vinyls for NFS Underground 2).

It's very difficult to find what I need in CS5, so here's my question:

Which version of Photoshop is the most basic and easy to use (user interface wise)?

PS: I'm running Windows 7 Ultimate 32b. Yes Jazz 2 works on it fine.
