yep, listen to mr EG...ive done the rounds now- been through 7 different pc soundcards. If id have just bought a delta 1010 to start with or whatever the equivalent was back then i would have probabaly saved hundreds....the delta 1010 is fantastic sounding, with a handy lillte bit of midi , and excellent latency whatever.... its worth thinking about where you see yourself 18 months down the line and paying that bit extra now...
Be it whether you are going to need more outputs (buy more than you think you will need) or you might have to swap to laptop or even mac based systems. Think about future compatibility with the way you see yourself working....
good luck with music!
