We have confirmed that R680 dual chip RV670 will launch on 23rd of January, together with Radeon 3670 / 3650 and 3450 cards.

It will be a full scale birthday launch, and ATI realized that it is better to launch them together than separately and one week after the others.

The final driver should be ready any day now, and Catalyst 8.1 will support all these new DirectX 10.1 55nm chips.

Expect many reviews on this in a week's time.
