Since my av reciever dont have 3d support but i want hd audio do i need to get a soundcard with hd audio support and plug that to av reciever and 3d playback graphics card and plug to my 3d projector? unless there is graphics card with 2 hdmi out put. currently my htpc using ati 5450 playing perfectly with hd audio output but iwant to upgrade my htpc to playback 3d and i think 5450 cant playback 3d.
I'm not worried about the sound cause i can already get HD sound from the 5450 but since my AV receiver doens't have 3D ready i wonder if i can get another graphics card ati 6570 (support 3D) and install that (since my MOBO have another spare PCI-E) then i can HDMI connect the 6570 to my 3D Projector and connec the 5450 into the AV Receiver to get HD audio.
Would that work instead of getting a soundcard or do i need to buy 2 6570 ATI to install just one type of driver?
