Well my new box is up and running, debian-amd64 official sid release and i must say it is blistering fast, but it also is coming along in stride towards the testing branch and then on to stable ... sid is currently the only working official branch of debian on the amd64 architecture to my knowledge and it runs xfce4 like a dream.
specs:
-Athlon64 3200+ Venice Core
-1GB low latency ram (i forget what brand and model)
-180GB SATA hdd
- nVidia GeForce 6200
... i know, nothing stellar but it is one hell of a jump over the pentiumIII box formerly known as pseudogen, which unfortunately had a power source failure reciently.
