The Logic Off Topic list

Hi Group!

Is there any advantages using multi-channel sound card in Logic (or 
in any other current seq)? I don't need multiple inputs or outputs - 
2in 2out is fine.
By multi-channel I mean internal "busses" like in Yamaha SW1000XG 
which I already have. It has only stereo out, but 6 internal stereo 
channels that can have onboard effects on them etc.
So, I'm planning to get a dedicated audio card (no synths or midi) 
and the question is: can I get better performance (more tracks, less 
cpu load etc.) with a multi-channel card?
I don't have Logic yet and I'm not familiar with ASIO things...

Thanks,

Jere
