I'm looking to upgrade my mid-2012 cMBP to the mid 2014 rMBP. Edit: The 15" top end model with dGPU. I'm trying to decide if the extra 700 bucks is worth it to max it out or not. I use xcode and adobe illustrator. The better resolution in retina is primarily why I'm upgrading. I can't find any benchmarks that show the difference between the 2.5ghz and the 2.8ghz. I can't imagine it being faster by much. Any thoughts on the 500 bucks for the 1TB SSD verses the 512GB it defaults to? I will probably keep this macbook pro longer. Probably until there's a better resolution or some other technology that comes out that I want.
