SPDIF only supports bitstreaming of AC3 and DTS audio. HDMI also supports DTS-HD, E-AC3 and TrueHD audio. HDMI also supports up to 8 channels of uncompressed audio, while SPDIF is limited to stereo. So HDMI is better. Of course, this only matters is your receiver actually supports those audio formats.

Quality wise it does not really matter much if you decode on PC or with receiver. Just try both and pick what works best in your own opinion. You can easily turn bitstreaming on/off with the Codec Tweak Tool.

Also, if you let the PC decode, remember that S/PDIF doesn't support more than 2 channels of PCM audio uncompressed, unless your sound card supports Dolby PCM compression(not sure what it's called anymore), which then allows up to 5.1 of PCM audio.

If you do PC decoding, it really is better to use an analog AUX line to the receiver: Use Line-out on the sound card and then Line-in on the receiver with a male-male jack plug.

On most sound cards Line-out is unamplified(which is good) but your receiver with amplify the analog signal. There's some audio quality reduction against HDMI but it's up to you if you actually hear the difference(most people won't).

If your receiver supports HDMI, use an HDMI cable and use your GPU HDMI slot and connect that with the receiver. If you only have 1 HDMI slot, you will have to use DisplayPort/DVI for the monitor, or if you have a receiver that supports video signals, use that.
