I have 2 iMacs right now, a 20" iSight G5 and a 17" Late 2006 1.83GHz C2D, but both of them are old and slow so I want to upgrade to the latest model. Although I have enough money to buy the top config 27" 2013 model and the employee discount I want to get the most basic 21.5" model (with employee discount). Should I get it? I plan on using it for internet, iWork, and music and video editing. For the music/video editing is this good enough or should I go as high as possible, maybe even buying a Mac Pro?
