Not at all.  In fact, I think in one of my old motherboards the built-in 
PATA slot was slower than the new PCI card.  Thus, I didn't use the 
onboard slot at all.

I suppose if you have a handful of cards running and you're doing 
immense amounts of I/O, it's possible you'll saturate the PCI bus, but 
I imagine you'd have the same problem with the onboard slot anyway.  
There's only so much I/O bandwidth to go around.
