Ok Cool, I didn't really like the idea of having both going at once because I thought it may cause dramas with gaming, but I guess no option. Thanks Sas and Purple.

What external DAC/amp are you getting?
Was about to get the Matrix Mini-i Pro. I read its great for the money. Looks good, compact, has all the connections I need for speakers + headphones. Apparently great sound too. It was recommended to me by a local store owner (along with other dac/amps), he uses it with his Fostex TH900 headphones, so I figure it can't be half bad and a step up from my Xonar Essence STX. There aren't many reviews around about it because its new so wasn't a quick decision. It was either that or the Quattro DAC/amp, but this is a larger setup and from reviews seems to be not better than the Mini-i Pro.
