Even though some imagine that the economic crisis affects all the sectors of industry, they are mistaken. Yesterday, AMD officially started to market the Radeon HD 5970, the Bi GPU graphics cards winning the title of the fastest product of the world.In a few hours, all stocks of the first production were sold. However this would not have happened except that the " Gamers" are way ahead and had already pre-ordere their cards costing close to 600€ each.In a certain way, this is similar to the sales of Mac that continue in strong form despite the crisis, whereas a good number of people declare that they are too expensive.
