If I were to hook up a Mac Mini or Mac Pro to a TV (via Mini DisplayPort > VGA adapter, or an Mini DisplayPort > HDMI adapter) and play a game like Call of Duty 4, will the visuals be as good as if I were playing it on a home console, like an Xbox 360 or PS3? I'm not saying "visuals" as in how good the graphics are, what I mean is the clarity of the signal. Let's say a normal game console (like 360) is hooked up via HDMI, how would that compare to what I said above? Also, I know most TVs have a VGA input for a PC, but how would I input sound? I don't think an auxiliary cable would work, because most TVs only have a headphone jack (for audio out). Thanks.
