Imac Compatible Soundcards, need more than 4 audio outs Options

[firepants]

Helooo.. I've just got me an O1v and am looking at getting a soundcard with ideally 8/10 outs for the various audio channels that i have in my logic set up. Unfortunately i have an IMAC G3 400mghz which seems unable to take the Audiophile delta 410 card that i wanted; i belive that i need to have an external soundcard that I link to logic via the USB port..Subsequently I seem to be limited to only 4 outs which for me is too few. I dont want to have 2 buy a new computer but unless i can find an external soundcard with the 8/10 outs that i want then I see no alternative..Please can someone inform me if such a soundcard exists out there and if its any good.
