In summary, it's very hard to recommend the Pentium 4 570J when the competition, AMD, is currently doing so well. I'd either opt for a cheaper 5xx model and overclock it, hopefully, to the 570J's default 3.8GHz clock speed, or go for any number of Athlon 64 CPUs. Dual-core Smithfield can't come soon enough, I say. Up until then, though, Intel's top-end desktop processors' performance won't be giving Dr. Hector Ruiz sleepless nights.
