That the GeForce GTX Titan X is a fantastically powerful card is something we already know. The card is in fact so powerful it's possible with stock (!) cooling to set new top scores. Jpmboy from the United States - a normal Enthusiast overclocker - managed to score a Global First Place in the 2x GPU 3DMark Fire Strike Extreme category with two of those Titan X graphics cards.
For the GFP, Jpmboy makes use of a Core i7 5960X clocked at 4750 MHz with custom water cooling. The dual GeForce GTX Titan X graphics cards are clocked at 1541/2000 MHz, resulting in a score of 17512 points. That's almost 300 points higher than 8 Pack's GeForce GTX 980 on liquid nitrogen!
Nice work Jpmboy, and it looks like we'll see a lot more from the Titan X in the future!
