The sonud is good, quality, i think it *MIGHT* have a problem with playing many sounds at once, sometimes in tribes2, i dont hear all the sounds that are happening, or it could be a problem with EAX
The smart card reader it for reading "Smart" credit cards theat have programmable info on them, its worthless to 95% of people, but the 2 usb with it are a redeeming feature.
Its a very good, stable motherboard
