Unless your games support SLI, you'll be stuck using one at a time. That's the reason why SLI/CF is never recommended except for those who have far too much money to spend.

then why would i get less frames on my games that support SLI as well?

The most likely reason is that something is off in the drivers and you should clean install them. If clean install doesn't help, it might be a bottleneck somewhere, maybe even thermal throttling (highly unlikely with that equipment, but possible)

When I did an upgrade to Windows 10 I had some unusual problems with this as well. I did it to try Rise of Tomb Raider's new DX12 mode. When DX12 was enabled it disabled my sli even when NV control panel showed it as enabled. I had to go back into Rise of and disable the DX12, did a full shutdown/restart and then a clean install of the Nvidia drivers. I know that may have been a little overboard, but everything was back to normal and perhaps a little better to boot. If you do reinstall the drivers you may need to re-enable your sli again.
