Update
Getting Closer
So I Uninstalled all drivers,
unplugged both cards,
put the card that I had in PCIEX8_2 into slot PCIEX16_1,
booted windows and installed drivers (280.19 this time)
then powered off and put my first initial card into slot PCIEX8_2,
booted and now I get to see two separate vga adapters in device manager, BUT the second one is now being only recognized as generic VGA adapter, with a status code of 10 (couldn't start)
I will now attempt without the bridge and see what happens, then attempt new set of driver installs.
