I can't remember if I asked this before, but it's back in my mind. I'm trying to decide whether I should get a high end 7.1 sound card for gaming, or just stick with the HDMI out of my NVidia GTX 1080ti card. It's going to a high end Onkyo A/V Receiver, THX 7.1 system. I've found lots of reviews on sound cards and such, but nothing that compares them against using the sound out of a GPU with the HDMI. Is it worth going to a high end sound card for gaming? Would there be a noticeable difference? One thing I do know is that GPUs at least support Dolby Atmos right now (with Windows 10), and there aren't any soundcards that do. My receiver is only 7.1, but some day I will end up upgrading it. Headphones is a non-issue at the moment. One, I don't have any. Two, when I do plan on getting some (hopefully in a couple of months) I plan on getting a pair of high end ones with a decent DAC like the Creative Labs E5. So for this post, I'm only focusing on 7.1 surround sound for gaming.
