Re: Using Optical Out in HTPC With Xfi.
Eh... looking at the two pics, I can't tell what the difference is between the two sound cards. Are they different brands or what? I would suggest responding back and telling us what the two sound cards are, manufacturer and model.
Having said that, I think both cards have an optical cable out. I suspect both will sound good and if that is what you want then both will suffice. However, the XFi cards generally do a good job at 5.1 sound and will off load more of the mixing from the CPU compared to other sound cards. I'm not sure if that alone is worth $100 though. Ultimately, your wallet combined with the amount of time you spend playing games will make the determination.
