Looking to purchase a mini computer for my entertainment center. I currently have 4 flat screens on one wall. I'm looking to buy something that will allow me to stream 3-4 different sports streams at the same time. One on each tv obviously. All in HD(720, or 1080). Without cutting out or lagging. I will have fiber gigabit internet. My questions are: What kind of processor will be able to do this without problems? How much RAM do I need? Anything else I should be thinking about? Video cards? I already have a keyboard and mouse. Trying to spend under $1000. Any recommendations? Thanks for the help.
