Gigabyte GTX 670 OC 2 GB
 

GIGABYTE's overclocked GTX 670 Windforce OC comes with a large and silent triple fan cooler and a full GTX 680 reference design PCB. This helps the card deliver out of the box performance comparable to the GTX 680, at a much lower price. Actually GIGABYTE is charging no price premium for their improvements, the card comes at reference design pricing of $399.
