NVIDIA GeForce GTX 670 DirectX 11 Video Card Review @Hi Tech Legion
 

Once again NVIDIA has launched their next generation video cards three months after AMD. NVIDIA promised that it would be worth the wait and even stated that they were not impressed with the new AMD architecture or performance. The NVIDIA 600 Series built on the new 28nm Kepler architecture is promised to show ground breaking performance the GeForce GTX 670 is built on the new Kepler design. Is it possible that impulse buy you made 3 months ago was a mistake?
