Snip: "The 3.2GHz Pentium XE 840 is offered as an alternative to current single-core Extreme Edition CPUs. It may not quite have the pure gaming performance punch as, say, the 3.73GHz XE, but it’s a better proposition when considered over a wide variety of applications. Think of it this way. The worst-case performance scenario is that the ?650 Pentium XE 840 performs much like a single-core 3.2GHz 640 model. The best-case scenario, that is, being run with apps. that take advantage of its 4-thread parallel processing ability, is performance that no single-core Pentium 4 could ever hope to match, even under the most esoteric cooling."
