First time poster but long time reader. I will be buying a new mac laptop by end of first week of July. Time frame is because of out of country vacation and travel. I will be using said laptop for email, web browsing, iOS Development(hobby) and light gaming such as Sid Meiers Railroads and Pirates, Tropico 3 and 4, Civilisation 4 as well as gog.com older games. My questions are as follows: 1. Will turbo boost allow me to run some of the games mentioned above albeit at lower graphics settings smoothly? 2. Will the turbo boost shorten the life expectancy of my processor? I definitely like the retina display of the rMBP 13 and if the new Haswell version arrives by the first week of July I will be getting that one. If it does not arrive by then should I get the new MBA 13" with Intel HD 5000 or the slightly older rMBP 13" which has the higher processor speeds but only the Intel HD 4000? Thanks for all replies in advance. I have been a fan of MacRumors and its forums for years.
