I know...
this is another what distro is best, but there is very little mention of the x86_64 ports.
So, the question is;
What 64 bit distro's are people using?
I've found that some of the 64 bit ports have a lot of problems with library trees;
I'm currently trying out the 64 bit version of Suse 9.3 pro, but it seems very bloated, and has a lot of problems. I've ordered Ubuntu 64 bit to try that out, as I've been a slackware user as long as I've used linux (since 1997!), but slamd64 is very unstable, and i'm going to be running a dual boot system with a major 64 bit distro, and slamd64 to iron out it's small problems.
I'm not a massive fan of click-to do -everything distro's as i'm very much a CLI and editing config files type of guy.This is what annoys me about suse.

So what do people recommend?

My system is an MSI nForce 3 mobo with 1GB RAM, AMD 3000+, and a GeForce 6200 Graphics card. So, it's MSI/Nvidia mostly.

If you like the command line and don't mind a bit of a challenge give Gentoo AMD64 a whirl

I have it running on a dual opteron board with zero problems

Tried Suse 9.3 which would'nt boot after the install, there's a thread on this board detailing the problem, seems to be a Suse's issue as opposed to hardware

Installed SUSE-10.0 x86_64-RC1 which does run but like you I find it too GUI orientated and don't feel at peace or in total control with it

Only issues with Gentoo are things like Mplayer and windows media files but there is already a Mplayer32 ebuild which works fine with win32 codecs and Mplayerplug-in32

To use flash in Firefox you need a 32bit version which again is readily available

These are'nt Gentoo specific there are currently no Win64 codecs or 64bit flashplayer

All in all I'm very pleased with Gentoo and will not be changing for quite a while

Yeah , go ahead with Gentoo.

I have tried basically all 64-bit versions of the top 20 distros at distrowatch.com and now I am using slamd64. This is by far the most stable dist. There were a few bugs during installation, but once installed everything runs fast and smoothly. I've had crashes in gentoo, suse, mandriva and debian-based systems. I'm not a very experienced user, so you shouldn't give up on gentoo just because I screwed it up. Portage is really the best package system if you don't mind waiting for it to compile. Otherwise apt is pretty good.
The problem with Slamd64 installation was segmentation fault, which was easily solved by setting up all partitions before the install. I also added the swap partition after the installation, so ...
don't give up on slamd64!

Ebsbel: yeah...I was the one that told Fred about the seg fault on the installer, which he has now fixed. I view slamd64 very much as a project level distro, and thus will boot to it when i feel like fiddling with things, but also wanted a major just-works distro...Have found it now with ubuntu 64, which i am very impressed with...it still gives you the power of the CLI, but has a couple (though not too many) of graphical tools if you're feeling lazy. Gentoo is too much installation work for me, and I like slacks package system...you know what they say, once a slacker, always a slacker!
