The problem with the Xonar DG is that it's a full PCI-E connection. I'm unsure if I can make that work, until I get my comp out on the table again and take another look. If I was going to crossfire gpus I wasn't going to be able to. But one card I ordered was defective so single gpu I can probably use a full pci-e connection. A PCI-E 1x would have been preferred leaving the option to crossfire gpus available.
Also, is the DG really that good? It's so cheap, like $30.
Edit: Was looking at the rear of the DG, has no indicated "Headphone" analog port, so then what would you do? If you ran an optical out wouldn't that render the sound card useless? My onboard has an optical port.
The headphones are plugged into the Headphone/Front out port on the DG.
