I have no idea if anyone is gonna see or respond to this as I am a tad l8 to the party but basically I play on ps4 love the game but can't be taking my ps,tv and sound system everywhere i am looking for a cheap laptop which will only ever run only rocksmith. It needs hdmi out 2x usb and I don't know if poss but an optical audio out port (i am not a pc guy) if anybody has any suggestions please let us know. if there is a desktop that is physically smaller than a standard I could go for that too
