Onboard USB 2.0 vs. add-on

[frunksock]

Is there any real advantage to onboard USB 2.0? Is there any danger of saturating or overly taxing the PCI bus with an add-on USB 2.0 card? Is a chipset with integrated USB 2.0 better from a performance perspective, or only from a cost/convienance perspective?

What I'm getting at is that the only chipset that seems to have everything I'd like (USB 2.0, DDR333, etc) is the VIA P4X333, which of course I can't find in any good-name motherboards due to the licensing issues.

So, if an add-on USB 2.0 card is going to be just as good performance-wise as that of Intel's ICH, then the SiS 645DX / Asus P4S533 starts looking very very nice. Thoughts? Thanks,

I don't think there will be any noticeable difference either way. So the expansion card is do-able.

in most applications, no

possibly if you run something like 4 USB2 external hard drives silultaneously off 1 USB PCI card then maybe.

personally i dont use usb 2 devices, nor will i anytime in the near future.

when i do, a PCI card is pretty cheap to get.
