Hello macrumors! Im looking to make an upgrade soon and Im going back and forth between these two options: Refurbished 15.4-inch MacBook Pro 2.6GHz Quad-core Intel i7 with Retina Display Originally released June 2012 8GB of 1600MHz DDR3L SDRAM 512GB Flash Storage and the current haswell refresh, 256gb 2.0ghz anyone care to enlighten me as to why I would want to spend 100 bucks more for a smaller ssd and haswell? Am I missing something? is haswell really that great? what about a maxed out current 13 rMBP? all suggestions and comments are welcome, just looking for some knowledge on the subject. I do a fair amount of work on Lightroom and Photoshop. as always, thanks for your time and thoughtful replies!
