What is the fastest AMD desktop processor?

The fastest AMD is the 1100T at $200...but it only ranks #45 in bench marks. Most any higher end Intel can beat it. The closest in price would be the i5-2500K at $217 which ranks #31 and can hit 4.0GHz with OC easily. The the i7-2600K at $314 ranks #9 and is far and away better than the 1100T with its "virtual" cores (multithreading) you have the use of 8 cores as apposed to the 1100's 6 cores. The 2600K hits 3.8GHz in turbo without OC and so far I hit 4.4GHz with mine. Just gets a bit unstable past 4.2GHz. the EFI bios is MUCH easier to play with.
