It would have even lower temperature than GTX 580.
So we will have GTX 480 performance at lower power consumption and heat.
And may be even higher frecuencys in overclocking...950-970Mhz.
Price i expect to be 369-399$.
Next would be GTX 560, 384SP, based on GF104, at 300$.
you can expect lower overclocking headroom for the entire GTX5xx series.

Semiconductors are a near-perfect power-to-heat conversion device, so a lot of work goes in to getting as much work done with as little power as necessary. This is compounded by the fact that dynamic power (which does useful work) only represents some of the power used – the rest of the power is wasted as leakage power. In the case of a high-end GPU NVIDIA doesn’t necessarily want to reduce dynamic power usage and have it impact performance, instead they want to go after leakage power. This in turn is compounded by the fact that leaky transistors and high clocks are strange bedfellows, making it difficult to separate the two. The result is that leaky transistors are high-clocking transistors, and vice versa.

the major complaint for gf100 is the high power consuption and high heat output, this is a direct result of leaking transistors and large channels which also provide the overclocking headroom (think AMD TWKR). becuase nvidia have spent the last year reducing leaking and refining the manufacturing process, we will have cooler more efficint processors that don't overclock as far. it's another trade off that is made clear when comparing AMD and nvidia gpu's, just like die size.

as far as the GTX570 is concerned, i'm always happy to see an increase in performance and a reduction in price!
