Oh okay, I thought it might since they have the same 700 series chip set.
There are rare exceptions for mixed SLI but this only happens when two matched cards differ only very slightly, an example being a differing amount of video memory, stream processors, or clockspeed. In this case, the slower/lesser card becomes dominant, and the other card matches. This depends on what cards they are - is your titan the titan black or Z?
