Today i had the pleasure of playing a little with a Dual Opteron machine.
It has a HDAMB motherboard (yeah , kinda old The HDAMC is already out).
I installed Windows XP-Pro + Service Pack 1 on it.

I haven't been able to run applications yet , hopefully i get to test 3dMark on it later this week. Should run pretty smooth on a nVidia Quadro card
