Crap, I can't find the article where Intel was comparing the Opterons to the Xeons that I was reading last night. It mentioned what the Intel guys used for GCC with -march on a Core 2 Duo system. However, I did find a Gentoo Wiki page where it says that safe CFLAGS / CPUTYPE values for EM64T CPUs is nocona: . The only thing is that they use gcc-3.4 by default as well as gcc-4.1 / gcc-4.2, so processor support may be better with the later versions of gcc. -Garrett
