If you want to install arch64, just read the wiki at http://wiki.archlinux.org/index.php/Arch64_Install_page.. I'm not sure if the ISO is updated though, so manually downloading the packages and installing them is probably the best way to go for now. As for stability, I'm running arch64 stable for a month now without any issues whatsoever ( yes, nvidia drivers too). Flash doesn't work, so be prepared to install the ultra useful flashblock extension ; )
I'll resume contributing once the server issues are sorted out. When I last updated, I changed the initscripts so that at boot up you should get "Arch Linux 64 0.7.1 'Noodle' " or something similar. syamajala please let me know if you want to call it Arch Linux 64 0.1 or whatever and ill modify it.
Great to see things finally picking up
