I assumed as much on the server quality cards.

Anyone know where information is on CPU usage on some of the lower priced cards? For me, it could be an issue considering my server at home is typicially the slowest CPU in the house. Right now it's a Celeron 300 (@ 300, rather have the stability on a box I never see directly then a small speed boost).

And I'm curious how well the gigabit NIC devices on Macs work.
