Hi, I am currently looking to buy a new Mac and I have settled on the 13" Macbook Pro with Retina display. I was just wondering how fast is it actually going to be. I am looking at the 2.6GHZ with 8gb of ram and 256gb of flash storage. I would really appreciate it if you can give me an idea on the speed (like what programs can I do on it and what is the max you can push it to). It would really help. Thanks!
