The internal sound cards don't even have Mac drivers, if you're taking the Mac Pro or Hackintosh route. I had almost forgotten that part being of particular use to you.
As for Thief 4...everything I've heard about it has basically been bad news, to say the least.
Yep, I love me some Mac, still prefer it and find it more reliable with less maintenance, I even found that for some reason when I had a dual-boot system that the stock Win8 install downloaded far slower than the Mac side (10x as fast, must be Ethernet driver issue or something with what came with Win8 Pro), but now that I have a legit Mac in a separate box... it's not as important. Part of me says "Stick with your plan you made 6 months ago! Get an internal soundcard for the PC and just use SC on the receiver with your console!" But I'm still living with the parents, trying to find a roommate who won't screw me over, and currently I have some space and setup limitations.
Anyway, just beat Heart of the Swarm (recommended, most fun I've had in an RTS!), so I'm going to eat something and pick an Xbox game to test the DSS + M-100 combo some more. Write notes. What do you guys think, some Halo 4/Reach, Batman Arkham City, Alan Wake?
AxelCloris,
The binaural audio looks promising, but to be honest, I'd turn off the binaural "beats" feature. I can tell the difference between game and life, but some things push too far, and I think I'd be too sensitive to that stuff based on my personal history with trying to use similar techniques, EEG feedback, and etc to have a positive mental effect... I don't like to be fully freaked out, it tends to stick with me longer than I'm comfortable with.
Also, seems like the audio is the main creative effort in that game, haven't seen much else besides general setting. Story, gameplay, graphics? They mention Occulus Rift, but that's about it.
May throw a few bucks at it anyway, just to support better audio in games.
