Been an Apple 'addict' since my first encounter with MacPaint and the 128K Mac. But, it turns out, I love Skyrim (and Fallout, really, really Fallout) more...just ordered an 17" Alienware with the 4GB 780M. I'm hard pressed to tell you what I am going to miss about my 2011 13" MBP. I still have my iMac and Mini, after all... The 5lb caryweight perhaps. Don't judge me. I've been dealing with 15fps in F:NV for years. I need 100fps.
