Hi, I currently own a Macbook pro late 2011... My specs are: 2.4 GHZ quad core I7 750gb Hard drive 8gb ram 6770M AMD 1gb grahics card 15" The battery has 68 charging cycles (I think there might be something wrong with that since when I game on my laptop it will lose battery even when plugged in and will charge for some reason. I think I will bring it to the apple store if the charging problem continues. Also the battery sometimes has issues keeping a charge). If I get the apple replaced will it boost my chances of selling it? ___ I went on mac2sell.net and they said my macbook pro is worth $1,750 I went on the apple website over "refurbished macs" and I saw that the macbook pro retinas are finally on there and it is listed for $1,850... Should I upgrade it to the refurbished retina??? I LOVE how retina looks compared to my non-retina 1440x900 resolution.... Also will the Nvidia 650m with retina be good for gaming rather then a 6770m AMD with 1 gb with a non retina? Or will it be worse since there are more pixels and it will slow down the graphics a lot??? __ Also do you think I can get more than $1,750 for my macbook pro since it has 0 scratches or dings (It has been in a case since day 1 and has been moved around a little bit).
