I currently have an iMac 5K It is a late 2014 with a core i5 (not sure on the ghz.), 8gb ram it does have an Nvidia card though and a 1TB fusion drive. My wife and I remodeled the home and we currently bought some new furniture for the living room and bedrooms and we don't really have any room for the small desk where my iMac currently sits. The extra room (office) I had is now going to baby #2 lol. I would be selling it to compensate. That being said, how comparable is this iMac to a lets 15" MBP. I say 15" because I enjoy the screen real estate when doing papers, light photo edits etc. To have multiple windows open without straining my eyes. This will more than likely be a stay at home computer due to its size/weight. Thinking of a 12" MacBook for portability.
