I guess I should have made a few clarifications as too my needs.
The sound card can't be a PCI slot card. My PCI slot is covered by one of my Graphics cards. It can be a PCI-e X1 though.
My only real speaker criteria is that I would like 5.1 sound. I am open to any speaker suggestions. It seems that 5.1 PC speaker choices are somewhat limited, but if I start to drift into the home theater speaker set up the choices get daunting.
I was looking at the Logitech z-5500s, but that is starting to get a little on the expensive side. Are they worth spending the extra money on them?
I also have a set of Sennheiser HD 280s that I got a good deal on a few years back that I use every now and then. So, a sound card that could deal with both headphones and speakers would be awesome.
If some one could suggest a good combination of speakers/sound card that meets this criteria I am open to suggestions.
