PNY GeForce GTX 670 @ Bjorn3D
 

The NVIDIA GTX 670 is one of our favorite cards at the $400 price range due to its performance, low power consumption, and relatively quiet operational noise. The PNY GTX 670 again follows the company's tradition of using the reference design from NVIDIA, but what sets the PNY GTX 670 apart from other reference design GTX 670′s is the lifetime warranty and price.
