A dual-core 2.6 Opteron is about US$1079. whereas
a single core is about $460. So for about $200.
more I can build 2 2.6Ghz systems that give me a
lot more bang for my buck than 1 dual-core
Intel isn't quite in play yet, since a dual-core
Pentium D doesn't give me the performance of a
single 2.6Ghz Opteron, so there's no point in
even considering it. Woodcrest/Conroe will change
things, of course.
Again, I'm talking about getting past the wall,
so the lower end stuff doesn't buy me anything.
