Recently I upgraded my system with another GTX 770 4GB, I've tried multiple different configurations within the Nvidia Profile Inspector application to only produce either worse performance, a very white screen, flicker, or at the very best, the ability to actually get an improvement on performance, with the occasional black square artifacts. I have searched the forums and various guides but no one seems to have the perfect SLI profile. Also I have tested each card individually and they do work in SLI for example GTA V.
