Gigabyte P55A or other brand? usb 3/sata3 `problems`

[hammill]

read in lot of places about this:

Hardware.info has some information about the PCIe bottleneck issues on Gigabyte P55A motherboards supporting USB3 and SATA3. There are 3 scenarios you could face using that board. One, your graphics card will run at half the PCIe bandwidth (x8) if you use USB3 or SATA3. Two, if your graphics card run at full speed (x16) or if you are on Crossfire/SLI (x8,x8), USB3 and SATA3 will run at half speed. Third, if you are running 3 graphics cards like tri-Crossfire or SLI+PhysX, you can't use x1 slots or the eSATA at all.

does anyone know if those issues solved somehow?
