When you deal with high-end graphic cards (high-end both in terms of performance and price), you soon discover that you are spaeking about racing machines eating a lot of energy, needing a very efficient cooling solution and usually bragging about their performance through the sound of noisy fans.
Here comes the announcement expected for very soon now of AMD-ATI X1950 pro graphic cards promised by PowerColor. They would be passively cooled (meaning no fan, no noise, but merely a high-tech high-efficiency radiator). It could become the most powerful graphics solution on the market in the “no noise” category. Since the graphic cards often are the biggest source of noise in the gamers PC, that would mean Revolution.
