I have the Audigy RX which supports EAX only up to 4.0, is it worth upgrading to an X-Fi just for EAX 5.0? How much of a difference would it make in Bioshock or Mass Effect? I am not even sure EAX makes much of a difference at all in Mass Effect but i correct me if i'm wrong.
From my experience, EAX 5.0 mainly provides improved audio positioning, better subwoofer use (e.g. for stuff like explosions) and a more immersive sound stage due to 128 hardware voices. How well games use that functionality can vary. I haven't played Mass Effect on the PC, but BioShock sounded pretty good on my X-Fi Titanium. If it helps, the best use of EAX 5.0 that I've experienced was in Quake 4, Prey and Battlefield 2.
If i understand correctly, Bioshock uses OpenAL under Vista/7, just like Doom 3, Quake 4 and Prey so Alchemy is not needed for this game and enabling EAX in the game menu is enough to make it work if a Creative card is installed, am i right?
Correct. There is no need to use ALchemy for games that support OpenAL.
Does running the game under Vista/7 with OpenAL allows to game to use EAX 5.0 or is it still limited to 4.0 because of the Audigy card?
OpenAL is just an interface which games can use to access your hardware. So you'll still be limited to EAX 4.0 on an Audigy card.
