Usb 2.0 cards bog down the cpu even if not being used.
You can see this in 3d mark scores.
As much as 1/3 less with a usb 2.0 card installed.
It is best to use a hub off the onboard usb.
This will also affect your hard drive speed.
Using onboard usb and offboard hard drive controller is the best config.
Try sata or scsi.
