Gigabyte GTX670 OC Video Card Review @ Ninjalane
 

Gigabyte GTX670 OC Video Card Review The Gigabyte GV-N670OC-GD2 has many things going for it starting with the new GTX 670 GPU. This may be a cut down version of the GTX 680 but it has plenty of power for most games and some to spare in others. Most of that power comes from the impressive decent factory overclock which was due, in part, to the custom designed PCB and Windforce thermal solution.
