Onboard sound/lan?

[new.puree]

Ok my motherboard says it has onboard lan/audio

I have a sound blaster live 5.1 sound card and a network card which both take up pci slots.
So on my current mobo I am using about 4 pci slots.
If you read the specs, the mobo I am upgrading to has only 3 pci slots.
I am currently using 2 additional fans that take up pci slots.
One for my video card and one for system exhaust.

I was wondering if Onboard lan/audio would eat up my systems memory the same way onboard video does.
Onboard audio quality can't be too bad right?

onboard audio actually uses cpu resources which basically reduces system performance. onboard lan is alright. i don't even think it uses cpu or memory resources. ur better of using that sound card of yours but make sure you disable the onboard audio before installing ur sound card
