C4D, 3DSM, Bryce, PS 7, and that's about it. If you're really interested on making graphics, get PS. C4D, 3DSM, and Bryce are mostly for wallpapers. In my opinion PS is the best program to make simple graphics. If you're a noob don't get C4D or 3DSM cuz they are kinda hard to understand and they are very expensive :wth:
I use several programs. Mostly Photoshop 7, Jasc Animation shop, Adobe Imageready, 3D Studio Max and Illustrator whenever I have to do somthing 'big'
