It's hot and noisy, and compared to the 5870 it's a little power hungry (though not outrageous); but it (1) isn't underperforming - its performance is just below the 5870, which leads to the fact that (2) it's $50 cheaper than the 5870 (sometimes even cheaper), therefore it isn't overpriced either. IMO, fix the issues with heat and it's a very solid card. But my question is: why are we comparing the 470 to the 5870? The 5870 isn't the card that the 470 is in competition with; the 5850 is. Compare the 480 to the 5870 and it wins, sometimes heftily, especially in tessellation. Compare the 470 to the 5850 and it wins, nearly always heftily. This is to be expected, they are more expensive than their ATI counterparts, but the performance boost is enough to justify the price.
