Summary: NVIDIA got it right once again. There is a perfect balance of price, performance-level, and power-draw, it all fell in the right place. The GTX 570 is giving you performance level on-par with the GeForce GTX 480, but at a very reasonable price, and at surprisingly good power draw, heat, and noise levels. In essence NVIDIA conquered the need to wait for and move to a new manufacturing process by simply working hard on whatever technology is available.
Pros: Reasonable price, Matches GTX 480 performance, Reduced power consumption, Native HDMI output, Software voltage control, Support for DirectX 11, Support for CUDA / PhysX
Cons: Still not as power efficient as AMD's designs, Power draw limiter could complicate advanced overclocking, Overclock out of the box very small, Still limited to two active display outputs per card, DirectX 11 relevance limited at this time
