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.
Max Support: 2x
As indicated by the PCI Express layout chart there are a total of two 16x PCI Express slots on this motherboard each using bandwidth earmarked for video cards. Slot two will be the primary video card slot and will run at a full 16x when only a single card is installed.
For best video performance you will want to populate slots two and five with video cards. This motherboard is pretty basic when it comes to expansion. You’ll get support for SLI and a couple of additional devices and that is about it.
