What are some things that I should watch for and enable that isn&#39;t so<br>
obvious for someone new to 64 bit?<br>

The first thing to decide is whether or not you want a pure 64-bit<br>
system or a 64-bit system that keeps 32-bit capability.<br>
<br>
I am a purist.  I left 32-bit programs in the dust a long time ago.<br>
But as a consequence there are some things that I will miss because<br>
they are available in 32-bit packages only.  An example would be<br>
Acroread, the PDF viewer, from Adobe.  Without Acroread, you will<br>
only view pdf files through the 64-bit xpdf.  The Intel C++<br>
compiler is another example.  In fact, most commercial software<br>
that bothers to release a Linux version will do so in 32-bit<br>
format only.<br>
<br>
So if you need to make use of those offerings, you&#39;ll need<br>
to keep 32-bit compatibility.<br>
<br>
My own view is that these software developers are way behind<br>
the times and should have long ago made their products in<br>
a 64-bit form.  It&#39;s not that difficult to do.<br>
<br>
Whatever the choice, pure 64-bit or 64/32, Gentoo makes it<br>
easy.<br>

Now I have a question.  How do I tell Gentoo to make it pure 64 or a mix of 32 and 64?  I have read about this but I don&#39;t think I have actually seen where it is set.  Is it a profile selection, USE flag or something else?<br>

<br>
If I decide on one then want to switch to the other, does that require a reinstall or just a change in settings and a recompile of world?<br>
<br>
Since I use KDE, I always use Okular to view pdf files.  I assume KDE is 64 bit ready.<br>

Try also running 32 bit app. System is not slower or anything else wrong happens. If You drop 32-bit support You cannot use WINE and load PE32 apps (aka Win32).<br clear="all">
