Our first conclusion is that the Radeon HD 4870 X2 manages to achieve its objective—namely to be the best performing card you can buy. It has been a long time coming, and other Radeons have had the same goal but have not been able to attain the same results. Case in point, look at the Radeon HD 3870 X2 which was launched at the beginning of the year. With this model, however, the advantage that the Radeon HD 4870 X2 takes over the GeForce GTX 280 is incontestable. It averages a 25% gain (with a peak at 51% in 2560x1600, plus eye candy) and above all, stays true in all of the games except for Flight Simulator X.
