Actually the Tesla line of cards are for data mining and neural network research.
Nvidia has 3 PC lines of cards
Quadro CAD/CAM and professional graphics.
Tesla for GPU compute. AI, data mining and other GPU compute functions.
The Titan is part of the GForce line and is a bit of an odd duck. It is a gaming card but like every other gaming card it can be used for AI, data mining, CAD, and even professional graphics but it is a gaming card. A very high end expensive gaming card.
