So i got a macbook pro retina 15" at the beginning of February (late 2012 version) and now since a couple of weeks the screen has been acting funny, I wouldn't say it's a retention problem, the screen kind of blinks, its quite noticeable on solid white/grey tones, for example on wallpapers with clouds it looks like the clouds are moving
, so I'm going to go to the Apple store and ask for a replacement /fix , the thing is, I seriously doubt that they would give me a new model since my laptop is already 8 months old, let's say the say ok we will give you a new laptop but they end up giving me a refurb model, is there a way for me to know this? 
Even if they give me a new model (late 2013 model) it's sort of a lose for me, the basic 15" model which is the one I have doesn't include a dedicated gpu, and I do play games on my mac
