I realize the talk is all retina these days. But I am torn. Graphic Designer. Primarily working with adobe cs 2014 suite. Most of my days spent in Indesign, Illustrator and Dreamweaver. Some big Photoshop projects come my way now and then. I desperately need to upgrade my 2009 iMac. It has served me wonderfully but it is way to slow these days. I am torn between the standard Retina 3.5GHz Quad-core Intel Core i5, Turbo Boost up to 3.9GHz 8GB 1600MHz DDR3 SDRAM - 2x4GB 1TB Fusion Drive AMD Radeon R9 M290X 2GB GDDR5 or the 27" with a Fusion upgrade and More memory added. 3.4GHz Quad-core Intel Core i5, Turbo Boost up to 3.8GHz 16GB 1600MHz DDR3 SDRAM - 2X8GB 1TB Fusion Drive NVIDIA GeForce GTX 775M 2GB GDDR5 Is more memory better than more pixels? and is the GeForce that much better than the Radeon for my needs. Pipe in. 2¢ welcome.
