I'm planning on purchasing a new computer in the next 4 - 6 weeks. I plan on getting a DVD-ROM, CD-RW, lots of RAM and 2 fairly sizable hard drives. One hard drive for system files and programs, the 2nd just to store music on. I'm thinking of getting a 100GB hard drive for the music and ripping files in WAV format and leaving them on the hard disc as I like to listen to music while I use the computer. Here's my question, is it worthwhile getting a separate DAC and getting a sound card with a S/P DIF input/output to feed into the DAC? I have a Linn Classik that I'll be using with the setup. Is this overkill and a waste of money? Should I just go with a CL or Turtle Beach sound card and use the DAC's on there and save some bucks?
