I'm building this for someone else, so I probably won't have the opportunity to tweak with the gfx drivers.
And now for something slightly different - SLI Options don't show up in the Nvidia Control Panel. I set up the machine with just the one gfx card to simplify the initial setup. I'm wondering if I need to remove and reinstall the drivers so Nvidia control panel will recognize there should be SLI Options.
The second card is visible in the device manager, the SLI Bridge is connected, and both cards have the power connection.
