[gentoo-user] gentoo on the i7

[luis jure <ljc@internet.com.uy>]

hello list,

after many years without a hardware upgrade, i'll be receiving my new
computer next week: intel i7 920 cpu, 6 GB ram, asus p6t mobo. 

i'm pretty excited, i imagine that at first i'll be shocked at the
difference with the ancient machine i'm using now.

now my question: searching a bit for the best compilation flags for
this processor, i found this at gentoo-wiki:

CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=core2 -msse4 -mcx16 -msahf -O2 -pipe"
CXXFLAGS="${CFLAGS}"
(http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel)

on the other hand, a thread at http://forums.gentoo.org says that the
wiki page is outdated, and that -march=native should do the job without
any further tweaks like -msse4 etc.

any ideas from the list?

best,

lj
