Well like the title says. I'm thinking about buying a MacBook Pro 15" the Middle model. Well actually i'm waiting for the next release of it. However, It is going to be more powerful than my current Dell desktop, on both CPU and GFX, well pretty much everything except Sound Card. I figured that when I'm at home, I will hook it onto the DVI cable on the 24" TFT, and external Keyboard, but I was wondering will it support my 5.1 sound system? This way I have a nice portable when out, and a powerful desktop when at home. I think I read somewhere that with a special cable, the built in connector supports more advanced sound than just headphones. My current setup uses 3 cables for sound, Green, Black and Yellow, I suppose it is Front/Back and Sub. Any Ideas?
