Im going to be purchasing my first Apple desktop computer in a few weeks after owning a 13" MBP for about a year. I know im going to be buying the 27inch model and then hooking up my 22" Samsung monitor for extra screen real estate (which cable will I need btw?) The main purpose of this machine will be web design. So programs like photoshop, etc will be the most regular programs run. I may in the future be doing some audio editing for podcast, but thats not the main purpose for this machine. Will the base model iMac with the 2.7Ghz i5 be ok? Or will I want to go for the 3.1Ghz model for the 1GB VRAM?
