I have two 4K Sony TVs in my home.  The pictures are fantastic, but the processors are slow and don't offer very high download speeds compared to my home network.  They were constantly buffering.  I purchased two of these computers, each with an optional warranty, and now enjoy seamless streaming and fast response times.  The specs on the computer allow me to do so much more than the Sony processors.  When I want to watch something online, like Thursday Night Football or a movie service, I select the HDMI input on my TV from the computer.  The image is better than watching it through my cable carrier.  I have had NO problems with either unit.
