Look at the price of this cpu.

INTEL XEON P4 3.2GHZ 533MHZ FSB S604 2M CACHE RETAIL BOX $1,695.38
CAD

That's Canadian dollars, but still a crazy price.

Any article that starts out by talking about the NX bit for memory
pages as being "hardware antivirus technology" is CERTAIN to be full
of technical errors. This article is no exception.

As you've correctly guessed, all of AMD's Athlon64 and Opteron chips
have this feature.

The old Athlon classic 1GHz processor sold for ~$1200 when it first
came out. The FX53 is priced at $799... Just to keep things in
perspective. Also remember that the chip this is competing against,
Intel's P4 Extreme Edition, tops the scales just shy of the $1000
mark.

Is it a rip-off? Of course it is! Every top-end processor is ALWAYS
a rip-off! Surely anyone who's been following these things for any
length of time knows that!
