Hi,

First post here. =A0I'm usually on gentoo user. =A0I'm in the proce= ss of building a new system which will be 64 bit. =A0I am looking for advic= e. =A0I would like people to post things that I might run into that one wou= ldn't expect and some things that are different from x86. =A0I was look= ing at something on my old rig and noticed the USE flag smp. =A0I didn'= t know about that until I ran up on it. =A0I learned something by pure dumb= luck.

I'm a long time Gentoo user. =A0Installed it at the early stages of 1.4= . =A0I also use KDE and have fluxbox installed as a backup. =A0The processo= r is a AMD Phenom II X4 955 @3.2Ghz. =A0It will start out with one 4Gb stic= k of ram. =A0I plan to expand that later.

What are some things that I should watch for and enable that isn't so o= bvious for someone new to 64 bit?

Thanks.

Dale

:-) =A0:-)
