cant say that cuz thanks to that chip you can use tri SLI but i realy have no idea how the PCI-e 3.0 work exactly , the NF200 is sort of an add on chip that works in conjunction with the intel chipset, so when multiple GPUs are detected, the NF200 chip can be accessed to deliver more bandwith to the third card. thats all i know about the NF200 . but wether it limits the board from using PCI-e 3.0 or not i have no idea....but to use pci-e 3.0 SLI you will need at least 2 slots of pci-e 3.0
