"With that said, with the exception of one multi-tasking scenario, the Athlon 64 FX-60 is the fastest all-round processor on the planet. The Pentium Extreme Edition 955 may be attractive to someone who often finds themselves wanting to do more than two things at the same time, but that market is limited to a few die hard power users. However, it's worth noting that there are rare occasions where I find myself running out of processor power with my current Athlon 64 X2."This is a pretty thorough review. There is even a pretty nice summary on exactly what dual-core means. While the bleeding edge processors never have the best bang for the buck, that is the price to have the fastest processor on the block.
