Hi everyone! Just sold my 4 year old mac pro today. I have been out of the mac game for awhile but am planning on getting a 27" iMac and I would REALLY appreciate the advice of those more knowledgeable than I on configuring it. Objective: Most bang for the buck configuration. A computer that will last me at least 3 years and be able to do everything listed below with speed. Uses: Work: Document writing, spreadsheets, powerpoints, Android development. Fun: Media such as web browsing, youtube, netflix watching and light gaming (think plants vs zombies, the walking dead etc.) Questions Low end 27" or high end 27" Fusion drive..yes or no? I would prefer a SSD but am wondering if it is user replaceable. Is a processor upgrade worth it? Or is that $$ better spent on Fusion drive? Is Ram user replaceable or do I need to upgrade? Do I need a graphics card with 1GB RAM? IMPORTANT: I have a 27"Apple display that uses mini display port. Will I be able to pair this with the imac for dual screen set up? Thanks!
