ZOTAC GeForce GTX 670 AMP! Edition 2 GB @ techPowerUp
 

ZOTAC's GTX 670 AMP! Edition is built around an unmodified NVIDIA GeForce GTX 680 PCB which provides a great foundation, on top of which ZOTAC is using a large triple slot cooler. GPU clock has been bumped by well over 100 MHz, which lets the card surpass GTX 680 in our testing, with a 3% performance lead.
