Definately stay away from Creative. If he's still looking at an all around solution, go with a TerraTec card. The audio is better suited for that. Other than that, he can use the sound built into the mobo for everyday use and get a good audio card for the music. In that case, check out solutions from M-Audio, Event, and Mark of the Unicorn. I do the same thing, and since I needed components that traveled, I'm using the MOTU MicroExpress for MIDI (4in, 6out) and the MOTU 828 for audio (8 in/out rackmount, connects via Firewire). This way I can use it on my main workstation for recording and mastering, and then plug in to a rackmounted pc (which is yet to be built) or a laptop for live sound reenforcement. Have him check out reviews in some of the recording mags like Electronic Musician and Mix as well.
