To be totally honest, Creative's recent drivers have been pretty solid. At the end I wasn't even using daniel_k drivers anymore. But yes, the Forte's drivers are very good (Auzentech actually JUST released updated drivers for the Forte earlier this month).
As Wolfram mentioned, X-Ram is basically useless as practically no games made use of it (I think UT2004 was one of them), but if I remember correctly, the Forte does have 64MB of X-Ram onboard. EAX has been replaced by OpenAL, but the Forte does support Creative's ALchemy software which will convert EAX calls into OpenAL so things should mostly sound right, from an environmental audio perspective, on older games. Wolfram is correct that it has Crystalizer and CMSS-3D (I use CMSS-3D for my headphones, which is nice with the built-in amp).
The Forte does also have all 3 audio modes (Gaming, Audio Creation, Entertainment).
In a nutshell, it's the best X-Fi card on the market, IMHO, unless you consider the X-Fi HomeTheater HD (basically a Forte plus HDMI).
