Its loads more than you need, and you won't be able to run a digital dj tool.

If you're starting out and want to crossover into digital djing, just start out with ableton and integrate it into a traditional dj setup.

Unless you're going to be running a load of hardware, you don't need many ins and outs on your soundcard, so the 828 whilst brilliant is overkill. Do you have an external mixer to work with? Again, if no you don't need a top of the range soundcard.

You can get top drawer sound quality from a 100 pound M-Audio card. Or maybe this?
