Default Argh...P7P55D PRO instead of P7P55D-E PRO

I just did a new build which I wanted to have USB 3 and SATA 6 support. However in my haste to get everything done quickly I selected the older P7P55D PRO instead of P7P55D-E PRO. I only realized my mistake when i opened my box yesterday from NCIX to see no sign of USB3/SATA6 on the motherboard box...ARRRGGGH!! I really dont want to disassemble everything and return the motherboard because thats gonna be a lot of hassle and take a few weeks.

Anyway my question is if I get the Asus U3S6 add in card later(when I have something that needs USB3/SATA6) will it limit the system bandwidth for doing dual crossfire? Or is adding the U3S6 card the same thing as having the P7P55D-E PRO or does the P7P55D-E PRO add extra dedicated lanes for USB3/SATA6 support??

Thanks.

AFAIK the USB3/Sata3 add-in cards will all be PCI-e x4 at most, so there shouldn't be any problem running it with a crossfire configuration (although on a P55 you're already down to x8/x8 no?). Most boards can still run an extra x4 slot with crossfire running at the same time no problem.

Installing the U3S6 addin card works identically to having a P7P55D-E model, it's just not build right into the mobo. If you look, you'll see that the PCIe 1.0 slot is missing on the -E model, it's because the SATA 6GB/s and the USB 3.0 are wired into it internally.

Thanks, that clears things up for me.
