AMD won't launch a new faster CPU based on the existing technology. Athlon FX74 and the Athlon 6000+ will remain the fastest parts based on Windsor core.
At one point AMD planned to introduce one more faster
version of Athlon FX family clocked at 3.2 GHz but this wont happen.
Even at this speed this CPU would not have a fighting chance
again Core 2 Extreme especially in games. The FX brand will have to wait for
its Agena FX part the native quad core CPU but you will have to hold your
breath for at least one more quarter, Q3 to be precise.
