The Inquirer reports AMD has been sending out the Athlon 64 FX-60 processors.
These are dual-core processors with a clockspeed of 2.60GHz.
They are in the hands of at least one INQ friendly box slinger now, so it is only a short period of time before they are in the hands of users.
You give up about 200MHz over a single core, but that small a loss is well worth the added second core.
If AMD follows form, it will be make a slight power increase over the single core, 110w vs 95, and the dual 2.6's will be out early next year in non-FX guise at a 95W power level.
