I use Gentoo for nearly 8 years, and of course, it will be Gentoo on
that new pc.
Besides desktop working, i am going to study and produce some image and
video synthesis.
I have some questions :
32 bits or 64 bits ? advantages and inconvenients ?
What CFLAGS have i to choose and what about kernel settings (Processor
type and features) ?

Thank you very much for your advices,

I just built me a new rig so I just went through the same thing.  This 
is how I did mine.  I booted a CD/DVD and used "lspci -k | grep driver" 
to list the drivers in use.  That helps a lot.  With that, you can use 
the search feature when doing the kernel config.


I went with 64 bit and used a miltilib profile.  So far, everything is 
working fine.  All my usual websites are working and everything.  This 
is my USE flags:

that since the * may mess up portage.  Since this list is supposed to be 
text only, I had to make them bold with the *.


Since you are using a nvidia card, read this too.

http://www.nvnews.net/vbulletin/showthread.php?t=118109

Basically, enable CONFIG_SYSVIPC in the kernel.  The nvidia driver won't 
load without that.  I have the following built into my kernel:


Symmetric multi-processing support
Enable MPS table
AMD IOMMU support
MTRR (Memory Type Range Register) support
Preemption Model (Preemptible Kernel (Low-Latency Desktop))

There are others but I think that is all that is different.

That get you started?

Re: [gentoo-user] 32 or 64 bits, CFLAGS and kernel settings ?

[Volker Armin Hemmann]

and all those questions have been discussed to death on this mailing list and 
the gentoo-amd64 list.

How about an archive plunge?

I cannot really recommend what I'm using and I certainly don't
consider this advice but I'm happy to share it. Note that in general I
tend to keep use flags limited in make.conf and then add them to
packages I emerge.

The processor is an Intel i7-980x, ATI 5770 VGA.

I think this conversation could result in interesting learning. (For
me anyway!) If there are things that improve performance then we'd all
like to be better educated.

Cheers,
Mark

[gentoo-user] 32 or 64 bits, CFLAGS and kernel settings ?

[Jacques Montier]

Hi all,

I am waiting for a new PC...
motherboard Asus P6X58D-E
Intel Core i7 950
4Go DDR
Gforce GT240

I use Gentoo for nearly 8 years, and of course, it will be Gentoo on
that new pc.
Besides desktop working, i am going to study and produce some image and
video synthesis.
I have some questions :
32 bits or 64 bits ? advantages and inconvenients ?
What CFLAGS have i to choose and what about kernel settings (Processor
type and features) ?

Thank you very much for your advices,

Cheers,
