Dont go there, is my advise if the display looks good, it is good. Many of these tests are deliberately designed to trip up the hardware, and completely non reflective of normal use.
MacRumors can be a source of great information, equally you really need to "separate the wheat form the chaff" The majority of Retina owners have no issue, including my own Mid 2012 Retina. Things with forums in general is people mostly come to solve issue, in some case complain, and a minority just to whine about hardware they have little or no experience with, barring ten minutes hands on at "BestBuy" which is clearly the case with some posts. This is the very nature of forums, on the polls here 80% - 90% are satisfied with Retina MBP, it`s the same every time Apple release a major revision; You can perform the same Google search for any given year the MBP has been in production and come up with a myriad of negative results;
2012 Macbook Pro issues
2011 MacBook Pro issues
2010 MacBook Pro issues
2009 MacBook Pro issues
2008 MacBook Pro Issues
2007 MacBook Pro issues
2006 MacBook Pro issues
So employing this logic, "one should never buy a Mac" on forums such as MacRumors, those with issue, those that believe they have been aggrieved and the "Haters" will always generate the most traffic for nothing more than their own personal motives. My own 2.3 Retina runs significantly cooler than my Late 2011 2.4 i7 15" MBP sat right next to it on the same desk, no loss in frame rate, no throttling at all, is quieter, to all intents and purposes the better machine by a fair margin.
Retina is just the next evolution of the MBP line, enjoy your Mac and forget about the rumour mongers
