I recently bought the new MacBook Pro (touch bar) 13 inch with the following configuration: Processor: 2.9GHz Intel Core i5 Memory: 16 GB 2133 MHz LPDDR3 However, the screen feels kind of small, so I'm considering returning it and getting the old model, but with a 15 inch display. The processor would then drop down to a 2.2GHz quad-core Intel Core i7 processor. If I went with the older model with the bigger display, would the computer still run well? I'm trying to use some relatively heavy programs like Unity and Blender along with some IDEs. Would the older model last me just as long? Any advice is greatly appreciated. Thanks!
