I got a delta 1010 going to a pc, the thing is with sound cards all of them reproduce sounds fairly well but only some record well. if you want to just use soft synths such as absynth etc then you might not need the ability to record samples direct on to your mac, but i have found it very useful because i can a, sample records and b, record my mixes on to pc for transfer to cd or mp3 etc, my advice is to get the best you can afford, check out your neerest shop and ask for prices. personally speaking most of the delta series is worth a look at. hope this helps
