From what I've seen, only the vga cables bring separate audio output for the PS3. The VGA ones always do. I'll check the instruction manual of my motherboard to see if I can use the SPDIF cable and buy a regular HDMI-to_DVI cable for the PS3 and then use the SPDIF cable for the audio on my PC. I think it's the best way to do it. And I barely turn off my PC so....

As far as the connection, I'd rather have the PS3 on the vga cable for the PS3 and the DVI for my two Radeon cards. I prefer having my computer have the DVI to the PS3. The PS3 is still going to look good and costs less than the two cards did. =P
