I already posted the link for the Fedora. DOH! (tired i am... my precious, my precious..)
Anyway, I just noticed that you will be running a 64bit proc. Thats a story in itself because of the lack of 64bit rpm repositories.
I'd say if the Linux o/s you choose will run on your 64bit system and there are enough applications that are ready made 64bit rpm's then that's the Linux o/s you should go for.
ubuntu is very smooth. Dunno about 64bit though.
You can start from http://www.Linux.org
and then check out either the iso's here (http://iso.linuxquestions.org/
) or http://www.linuxiso.org
As a note my first Linux o/s was slackware after Linux on floppy disks. Then came Mandrake and RedHat at the same time. Both are nice for newbies because that's what they are marketed for. Nice graphical installation thingies, etc. FreeBSD was in there before Slack, but that aint Linux and I found out about FreeBSD from running BSD a long time ago .
IF you have lots of time and bandwidth download as many distro's that support 64bit and then experiment. Thats what I've done or rather what I had someone do for me. All those distro's in my profile.... I use 'em all. OpenSource is fun and one day you will say goodbye to Microsoft Windows forever just like me and the many satisfied and now wealthier Open Source users worldwide!
