Sapphire announced that its Radeon HD4870 would be available in France in the coming days at 249€.
3Dguru has a nice review of the upcoming Radeon HD4870 graphics card. It’s supposed to be the fastest offering from AMD and it is stacked against the GTX260 from nVidia, cheaper Radeon HD4850 and older nVidia GeForce 9800 GTX.
The conclusion is that the HD4870 is going to be a tough competitor for the much more expensive nVidia GTX260 (expect nVidia to cut down prices quite quickly to compensate).
