well the 690 is nice cause its dual gpu. The titan just got its a33 whipped by the 780ti so the titan is no longer a saught after card unless you are rendering and need the 6gb ram. The 690 is a older card but its still pulling great numbers for sure. Its a toss between the 690 and the 780Ti i'd say. If it were me i would grab a EVGA classified edition gtx780Ti with the new acx cooler.
