Yes that's my understanding also, but this is a brand new machine to
me, Gentoo based where I can set all my gcc flags pretty easily, and
for the Core i5-661 I'm not finding much info on what's recommended
for gcc. -march=native? Or maybe use specific settings such as those
for an i7?

I'm just grasping around for ideas mostly.

Thanks!
