CS:GO may be an exception, though, if they left the snd_use_legacy_surround variable in the Source engine for that iteration. You'll have to point ALchemy to the root CS:GO folder for it to work properly, though, since it activates the Miles Sound System's DirectSound3D implementation.
Bit late to the party on this one guys, but I confirm here that the "snd_legacy_surround 1" command is working fine with CS:GO!
So yes, when you apply ALchemy to the game OpenAL (or DS3D, which it originally is) and EAX will work!
Because of that creatives CMSS-3D will blow asus' dolby heaphone completely out of the water because its not just 5 speakers downmixed to stereo, but the actual game coordinates of the source of every sound are used since these are retreived with OpenAL. (I might be biased here as a creative user, but I think you could call it a fact that in theory using raw coordinates of sounds should give more accurate positioning than 5 channels being downmixed)
I use a Q701 through an M-Stage with a Titanium HD and this is really the first time in a game I can truly say I can hear ANYTHING coming from ANYWHERE.
Of course it's still a bit personal since you just need to be lucky that the HRTF of your headphone surround emulation algorithm commendates with your own ears/head.
On your issue of support:
As long as the card stays supported, I guess it's CMSS-3D feature will do so as well. And as long as the operating system supports OpenAL you should be able to use ALchemy, because the only thing it does is "translate" DS3D to OpenAL, because Vista/W7 doesn't support DS3D but does support OpenAL.
So long story short, as long as OpenAL and your creative card is supported by your operating system (which it most probably will,.. at least with W8), all the old OpenAL/DS3D games will keep working just as fine with CMSS3D as before.
Wouldn't get your hopes high for fancy audio in games in the future though...
