What I will tell you is that the clock frequencies on these boards surprised me, the GeForce 470 seems to be clocked at roughly 650 MHz, that's lower than I expected. And that indeed will have an effect on performance. I think it's safe to that the GeForce 470 and 480 will be worthy competitors towards the Radeon HD 5850 and 5870. Will it be a knock-out ? I doubt it very much. But is it important for NVIDIA to deliver a knockout to the competition ? Well they would hope so, but no .. not really, as the current performance levels that ATI for example offers simply are superb already. Being six months late to the market does pose an issue, ATI will already be respinning and binning their upcoming products, clocked higher and they could match NVIDIA in either price or performance.
