Well, I finally gave up on my Macbook Pro with the notorious AMD GPU issues. I bought a high end 5k iMac and a low end 13.3" Macbook Air when mobility is needed. Still, the 2011 Macbook Pro (17") is usable to some degree when used with gfxcardstatus forcing the integrated GPU, and when no GPU intensive tasks re running (especially Apple Preview, surprisingly). I would appreciate some ideas of uses for this laptop. I already have a NAS, so no need for that. I might consider using it as an extra processing cluster for Compressor, but that's a very niche use that mostly is not needed. Remember I cannot use any external monitor due to the failing AMD GPU. Your thoughts are welcomed. Thanks.
