P8Z68-V-LE SATA ports taking bandwidth from x4 Lane


I have a P8Z68-V-LE motherboard which has a x16 GPU lane and a second x4 lane. I'm considering cross-firing two GPU's on it (and yes I know it's slower than 2 x8's... didn't realise that it was a x4 lane when looking at the specs, must have accidentally skipped over it!) and I was wondering if the SATA ports or anything else takes bandwidth from the x4 lane which will slow down the crossfire configuring even more.

    Hi, SATA dont share bandwidth with pcie. But pcie x16_2 slot will share bandwidth with 2x pciex1 slot if you install on pciex1 slot.
