thanks for the link and the info. so you think atom processors are fine enough? the latency actually doesn't matter in my case. i'm more worried that i'm going to through a lot of CPU heavy stuff on it, as this will run experimental software I wrote myself (and I won't have any time for performance tuning of the software itself).

Yes I know about MOTU. But that's the asset I have, so it would save me money getting an additional interface. If the onboard sound can go to 8x analog that would be perfect, otherwise I will need to add a cheap multichannel sound interface. 8 chans would be minimum. your presonus is definitely out of the current budget.
best, .h.h.
