Hi. I'm a noob to Mac. I bought 13" mid-tier one I found the screen to be too small. So, I'm thinking of buying this late 2013 MBP 15" (refurbished): 2.3GHz CPU 16GB of 1600MHz DDR3L SDRAM 512GB Flash Storage Intel Iris Pro Graphics and NVIDIA GeForce GT 750M The 16GB of RAM would expand the lifespan of this notebook - I want this laptop to last for at least 4 years w/o major slow down. I'm expecting to see a new lineup of MBP in September or Octorber. Does refurbished products' prices drop dramatically when new ones come out? If so, by how much? I'm also curious if the Geforce GT 750M will be powerful enough to run games like Diablo III and upcoming Civilization in fall (both support Mac natively). I might use external 1080 FHD monitor for these since the native retina display's resolution seems too high for this discrete cpu to handle 3D games. I know I know....Mac is not for gaming, but for light games like those.... May I have some experts' kind advice please? Thank you.
