    Multi GPU Index

    The Hardware Asylum Multi-GPU index is a portable set of data we can use to determine the multi-gpu potential of any motherboard.  A higher index number indicates a favorable condition for multiple graphics cards while a lower number indicates a hindrance in one of our leading indicators.  Since the Index is not dependent on system architecture it can be applied to any motherboard regardless of processor or chipset generations.

    As indicated by the PCI Express layout chart there are a total of three 16x PCI Express slots on this motherboard with two of them using bandwidth earmarked for video cards.  The configuration is rather unique because you are given a choice of bandwidth allocations depending on your system configuration and processor selection.

    The top two 16x slots use bandwidth directly from the CPU.  This configuration changes if you are using a 44, 28 or 16-Lane processor where the number of lanes to each slot will change.  At first I found this to be a little strange however it makes sense to run an dual 8x configuration for a 16-Lane CPU as it simplifies the lane switching for larger processors. 

    For best video performance you will want to populate slots #1 and #3 with video cards but, you already know that given how small this motherboard is.
