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. In most of the latest DirectX 10 and DirectX 11 games, the GTX 570 will provide you comfortable gameplay with quite some eye-candy enabled, at 1920 x 1200 resolutions. It will also make gaming at 2560 x 1600 possible with some loss of detail.
The ASUS GeForce GTX 570 card is a decent product that sticks to the reference design from NVIDIA. As a tiny bonus that doesn't affect the price, ASUS stepped up the clock speeds. ASUS' in-house voltage control software certainly complements the voltage controller well, to help you overclock the card beyond what the stock voltage is capable to provide you. The reference design cooler provides a decent level of cooling, and isn't very noisy. In all, NVIDIA struck gold with the GTX 570, the GPU that may very well be the card of the shopping season. ASUS did its job as a reputed brand selling the reference design well.
