For example an H81 pro btc has 7, that means you can’t have more than 7 GPU’s connected on that motherboard! (Integrated GPU on the motherboard + 6 GPU = 7 GPU total)

each Motherboard has a FIXED MAX PCI-E support.If there are no major changes, then you can skip this step.( Chipset, PCI-E, GPU support changes are the most important ones and you NEED to upgrade your Motherboard BIOS if they came out).
