This is probably a dumb question but if I get a mobo with onboard X-Fi, will that support everything the "actual" X-Fi supports (such as EAX 5.0 and the like)? I was under the assumption that an onboard X-Fi is no different from an actual card but with you guys saying "onboard isn't even close to actual card in games" I can't be too sure now...
I haven't really looked into the onboard X-Fi solutions, but I wouldn't assume its a full-featured X-Fi based on the size of the add-in cards vs. the space typically allocated for onboard sound solutions. It should support EAX 5.0 for sure, but extra stuff found on some of the higher-end cards like ASIO etc. might not be included. I seriously doubt X-RAM is included but its a pretty useless feature anyways.
Also, depends a lot on who is providing/supporting the drivers for the onboard X-Fi, the mobo maker or Creative. I know a lot here think Creative's drivers are less than stellar, and they could certainly be quicker with updates, but if you need to rely on the board-maker for driver support that'll generally mean slower/worst driver support. If you can use either Creative's drivers or the board-makers drivers you should be in pretty good shape here.
Lastly, for the sound you actually hear in games. Again, can't safely assume it'll sound as good as an add-in X-Fi for many of the reasons listed above. Shielding, quality of components used, etc. will all factor in. Your DSP will be the same, which will enable EAX 5.0 and the spatialization/game effects, but the DAC, other onboard components and speakers will determine how that translates into what you hear. The one nice thing though is that you should be able to safely assume your onboard X-Fi won't run into the crackling/popping some complain about with various South Bridge chipsets since that's something Q&A should ensure against.
