I finally wanna make the switch from PC to MAC so I'm getting the one with 256GB SDD + 2TV HDD. Can I install Win7 on the hdd? Don't really want to use expensive real-estate from the SDD for it. Can I use THIS to upgrade to 16GB RAM? Do games still look good when playing them in 1080p instead the native resolution? I read how terrible lower resolution movies looked on it so that got me a bit worried. thanks!
