Your desired specification seems very low for someone with a budget of up to £3000. I use my computer for music and graphics. On the music side of things, I use... Yamaha DS2416 which is a 32bit 96,000Hz 16 channel digital mixing board based on the Yamaha O2RYamaha SW1000XG which is a mother of a Audio/MIDI card - internally cable linked to the DS2416 Yamaha AX-44 which is an I/O unit which is internally cable linked to the DS2416 ...which when I bought them five years ago, totalled £1200. Needless to say, they're very good, even if Yamaha aren't so hot with driver support at times. You could still pop the Audigy in there as well. As for HDD space - if you're getting two SATA disks then make them 200GB because you can never have too much space. I have a SATA Maxtor 200GB /w 8MB cache on which everything runs, with a same spec PATA Mactor 200GB /w 8MB cache disk for storage. It may seem huge to start with but really it isn't.
