ah thanks for the reply, ermmm, i just checked the nvidia site and it says the card is capable of 7.1 sound so hopefully i think with one HDMI cable from PC to AMP should be ok, but i was just not completely sure lol.
This is what it says on the nvidia site : HDMI 1.4a Support
Support for HDMI 1.4a including GPU accelerated Blu-ray 3D support, x.v.Color, HDMI Deep Color, and 7.1 digital surround sound.
Any confimation on this would be great, thankss
