Earlier this year, NVIDIA released the GeForce GTX Titan as an alternative to multi-GPU cards, giving users additional freedom in their product choice. With a price of USD 1000 and strict limitations, it was meant for a limited few, but those few who bought one were extremely pleased.
Restrictions by NVIDIA even prohibit placing a sticker on the card, which makes ZOTAC's GTX Titan AMP! Edition look exactly the same as NVIDIA's reference Titan. All Zotac could do was adjust clock speeds, and those are now 902 MHz GPU and 1652 MHz memory.
