Gigabyte G1 Sniper Z87 Motherboard Review

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.

Index: 3.75
Optimized: 1x
Max Support: 2x

NVidia SLI
AMD Crossfire

As indicated by the PCI Express layout chart there are a total of two 16x PCI Express slots on this motherboard.  Slot two is your primary video card slot and will run at a full 16x when only a single card is installed.  Slot Five will accept 16x video cards but is hardwired to 8x using bandwidth from the Z87 chipset. 

For best video performance you will want to populate the top most PCI Express slot with your video card and try to avoid using the secondary slot.  Given the distance between the slots if you choose to enable SLI or Crossfire be sure that your bridge connector is long enough to reach.
