ATI focused on its Radeon HD 3850 256MB at launch, as the card was low priced and it was selling well, and now it is time for the 512MB version of 3850 and the Radeon HD 3870 cards.
Despite the fact that the 8800 GT 512MB is faster, there is a demand for Radeon HD 3870, as some people really like the HD features (where ATI clearly wins) and the fact that the dual slot cooler is quieter.
The Radeon HD 3870 price will soon drop below €200 and this will make it an even more attractive option. However, AMD might have some trouble selling these cards in the case that Nvidia miraculously manages to satisfy the incredible demand for the 8800 GT 512MB.
If only Phenom was a bit better.
