The GeForce GTX 780 is NVIDIAs all new high-end graphics card based in their Flagship product, the GTX Titan. This means it is based on the GK110 GPU and has an whopping 7.1 Billion transistors. That makes it a nice chunk faster opposed to the GeForce GTX 680 GPU. We test the product with the hottest games like Metro: Last light, Battlefield 3, Sleeping Dogs, Far Cry 3, Medal of Honor Warfighter, Hitman Absolution and many more.
