I've been using the Sound Blaster Z for the past 6 years now. I really love this card and it's been working Flawlessly. I'm connecting via Toslink to a Yamaha receiver using the 5.1 surround sound via the Dolby Digital and DTS software built into creatives software panel.
My question is what kind of signal does the EVGA NU output via Toslink to a digital receiver? Dolby or DTS? PCM?
It SHOULD be able to output the same codec as the source unless the codec is too high of a bandwidth for the Optical connection. Toslink supports any stereo resolution up to 24bit/192khz PCM, does not support DSD stereo. It CAN output Dolby Digital 5.1 and DTS 5.1. It does NOT support Dolby TrueHD or DTS-HD MA or Dolby Atmos. Basically, any form of uncompressed 2 channel audio (other than DSD), and only compressed multichannel.
I would assume the software will have options to designate what your preferred output format is, but there is no sense of converting DD to DTS and vice versa.

Would using a sound card take up less system resources than using a DAC over USB? I assume using USB audio would load the audio processing onto the CPU. Back in the day using a sound meant unloading the process from the CPU which was a perk. Or does it even matter anymore?
Out of curiosity, does your external DAC have an Optical Toslink in? I personally like Optical over USB far more, Mobo Optical out to DAC Optical in. Have had much greater success over the years. Also, mot all USB DACs support 2 channel 24bit/192khz while pretty much all do over Toslink.
