Hi All, Trying to gauge the future of my 2010 Mac Mini (500 GB HDD, 4 GB ram). Primarily used as a streaming device for my TV, but over the last year has struggled to stream in HD without lag. My 2013 MacBook Pro does not have this issue and has taken over the job. For the Mini: is this an issue of HDD or Graphics Card? Don't mind updating to SSD, but want it to fix the problem. Thanks for your help!
