Graphic design software program is used for multi-media purpose, graphic designs, to emphasize image development, technical illustration like car engine designing or as we say to use it access graphic files. There is some best software of graphic designing:
adobe Photoshop
Adobe illustrator
corelDRAW graphics suite x5
Adobe indesing
Adobe flash
Corel paintshop photo pro x3
Art rage 3.5

I say Adobe Illustrator, Adobe Photoshop, and Adobe InDesign. Those are what pros use. They'll cost you $600-$700 each. If you're not wanting to become a professional graphic designer: Apple's Pages will do if you're a Mac user.
