I have a 2009 2.26 Core 2 Duo... it's in good shape. I tried streaming my 1080p iTunes content to my tv 3, but noticed that it isn't as sharp as streaming from more powerful computers. Maybe it is my eyes. Is there a minimum in CPU power to streaming 1080p content through iTunes to TV? I am hoping to make it my dedicated streaming server but am wondering if it is worth it. Is there any upgrades I can do that will help with the streaming? Thoughts?
