The AMD FX-60 is due out on January 10, 2006.
It's dual cores that clock at 2.6GHz. Preliminary reports are that it will be a decent overclocker, early samples went to almost 3GHz on air, with little or no tweaking. If you couple it with the new NVidia 7800/512 cards, you will be easily able to break the 15K barrier in 3DMark05.
So, this will be the gamer chip of choice for some time to come.
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.
What are you thinking? I think you will love the progress.
