I see conflicting information in that page. The picture shows the ATI Radeon HD 4350 512MB + LP Bracket VGA,DVI & HDMI but in the Description it shows: GPU Model: Radeon X1650 Connectors: DVI, D-Sub which is an old card...
i have just spoken to them and it is the ATI Radeon HD 4350 512MB that they have,
any opinions of that video card, has it got inbuilt audio?
if its the sapphire 4350 they show in the picture (why do they link Asus as the manufacturer?) then you are good to go. The HDMI port out will include audio and video.
