I'm running Fedora on an 8RGA+. I've had no particular issues with Linux. I have had some difficulties with the Firewire disabling USB ports when I turn it on, but that happens in Windows, too.
I am indeed looking forward to Fedora Core 2, because the ALSA drivers seem a lot better than the OSS ones for sound.
Like someone else said, the only hitch with the video drivers is to yank the generic TLS libs, because nVidia's installer doesn't move them.
