IO Level Up on Asus P7P55D-E LX

Hey guys, just want some info on how this works. It says on Asus.com that it cuts the Pcie bandwidth from x16 to x8 and accelerates the SATA III and USB 3.0. I will be using a GTX 460 and I want x16 with a single card. Will this cut me off and present problems?

  1. yes it will cut into x8. But you'll not notice the difference between x8 and x16 bandwidth even with a 5870!! so don't worry.
  2. So with IO level up turned on it will cut the single pcie link to x8? Why is that?? I know the higher end asus p55 boards don't have this so it was a little fishy when I noticed it.
  3. Yes .. I'm also disappointed.

    And I have another question ... the motherboard only really have USB3 and SATA3 if I change the pcie to x8? or USB3 and SATA3 are allways there and "yo level up" only increases a little their performances?

    Why do you say I will not feel the difference between x8 and x16?

    Thanks
