Phunktion: You're going to have to go read some reviews. Phillips has 3 models. I believe the one everyone is talking about here is the Acoustic Edge. It is in fact 5.1. In fact it's the only card on the market to be able to output a normal 2 channel sound source in 5.1 format (actually generates a 5.1 soundfield from a 2 channel source). Has LR front output, LR rear output, and Center/Sub output. All you need is 3 pairs of speakers. Awesome card, goes for $99 retail. Only knock is that it has no optical IO, just digital coax. Can still hook up to a 5.1 receiver, just no optical.
