i have a couple of amd servers i dont admin them but i check them from time to time, they run great i dont know what u have going but on 1 amd system is a 2.5 ish 1 gig ram 1 60 gig
on that server they have a forum 65 normal active users, game server stats, and a game server, ftp, and more. seems to run fine.
the line that its on is unbeatable, it hosted at Level3 Com, Cali Silmar its good to have friends
sorry for being off topic
but i would say the Xeon SCSI is great
