Absolutely correct. SCSI controllers tend to outlive multiple mainboard purchases, and if you aren't a rabid Adaptec fanboy, there isn't even an initial cost saving in getting onboard SCSI. Offerings like LSI's or Tekram's U160 and U320 controller cards are excellent performers for low prices. Also mind, U320 makes no sense unless the mainboard's chipsets has the fast PCI or PCI-X bus to feed it; on "normal" 32-bit 33 MHz PCI, U160 is already (slightly) bottlenecked, and U320 makes absolutely no sense.
