Hmm, good point, didn't quite look at it that way. But now I'm wondering if there are motherboards out there that radiate a little bit more than they should, and force peripheral vendors to do extra work clipping EMI in their own products. This is probably not true, since all PCI card vendors would have to test their products with tons of different boards.
