I just bought another 550 ti, one is a msi i belive and the other is a pny, i have both installed and both show up in device manager. But no sli option i have a sli bridge connected and i also have updated my comp bios and my video card drivers, but still no sli option. I noticed that my video card drivers are different but should that matter if so how can i slove that.

Delete all the drivers and reinstall with both cards in. Make sure your board supports SLI!
