I am thinking of getting a Mac Pro again, I have found a stock build 2012 Mac Pro W3565 6GB RAM etc for $200. (seller is downsizing). I would drop a x5690, max out the RAM and get a GTX 1080 for it, so the price will jump up. But I am wondering how much longer it will be before Apple stops supporting the hardware in their OS. I think I saw that they officially dropped the 2009 already, so I worry if it will be maintained much longer.
