Finally, I turned my computer off and re-seated my two GTX 980s. I even swapped them around. This was after I uninstalled the cards from device manager.
Finally, after re-booting, the SLI option appeared.
On Saturday while playing Syndicate, I crashed mid-game, and had to re-boot my entire system. When Windows came up... guess what... no SLI option. I swore out loud. This time, instead of unseating both cards, I switched off the power of my computer, unplugged it, and depressed the power button for a good 15 seconds. God I was mad as hell, thinking I was going to have to re-seat the cards anew with each and every crash.
Thankfully, when I re-booted, SLI was there - and it's been there since.
Please let me know if it works out for you. Is it the driver or the monitor? I have no idea. BTW.... something weird is still going on for me... when I turn on my screen it's blank right up until the Windows logo appears. I should be seeing another screen that prompts me to press F2 in order to enter bios. I'm not seeing that screen. I only see it if I pull out the monitor's cable and plug it into my other GPU.
Bizarre things are happening. If you figure anything out then please let me know.
