Right the pcie controller is on the cpu do you agree?
So if the controller is on the cpu and the traces are identical (They are) then why wont a single graphics card work at 16x gen3?
The switch is only used one a 2nd gpu is inserted
Cadaveca it could come back and bite everyone in the ass though apart from gigabyte.

correct the controller is on the cpu but the traces, sockets ect are identical so in theory every board manufacturer could give you pcie3 support for the first slot but only Gigabyte did this.....why dont the others???
You decide but i know why
windows 8??? windows 8 doesnt need UEFI.
Even OA3 doesnt need UEFI which is for large SI's as the bios strings can still be built into older bios's.
Also on the UD7 Gigabytes board if I remember rightly doesn't activate the NF200 chip until 3 or more pcie16 lanes are used which is different...
Looks like after MSI's mud throwing they may end up with egg on there face!!!
Hmmm gigabyte = Dual Bios + No UEFI :)
