Hello there,
I've been reading up about the usb3 chipsets, and speeds that many motherboards can get with them. Currently we don't have much to tax them, with future ssds and video capture cards when they get more popular may actually use it's full bandwidth available.
I have noticed that for H55/P55 based boards, It is likely impossible to get it's full promised 5gb/s transfer potential rate. This is because it may be running in "half speed" mode, detailed here:

In short, it seems to be having the usb3 chipset on a pcie Gen1 bus, running slower.
I'm a bit annoyed at this, because I want to actually run a Intensity shuttle usb3 device (it captures hdmi, and will likely want the full bandwidth available).
I've noticed that also on that page, Gigabyte and Asus have come out with "Turbo" or "Super speed" options, which give you a genuine full usb3 busspeed, by sacrificing your gpu pcie lanes from 16x to 8x.
I guess my question is, could I do something similar on the itx boards (I have a gigabyte h55n-usb3), or set my gpu to run at 8x in some way to emulate this?
