I'm looking at getting a new card that supports bitstreaming. I was looking at the brand new GTX 560, but also the 6000 series (69XX specifically), as my board only supports Crossfire. So to anyone with a 6000 series card, and also runs Linux, how is it? I don't need bitstreaming support under Linux, but I will be using the HDMI port for my audio. I just need decent support via the Catalyst driver. I've strayed from ATI since my X850, so I'm completely out of the loop
