So I've had the MacBook Pro 13" Base model for about 4 days and I've decided I want to return it. I was thinking about purchasing the Macbook Pro 2015 2.7GHz Dual-core Intel i5, 8Gb ram, 256GB PCIe-based flash storage, Intel Iris Graphics 6100. Do you think this model will have about the same performance as the MacBook Pro 2016 base model?
