hehe my old dual opteron sytems seems to have gained a nice boost with win 7.
Previously with xp pro64 (tweaked for numa) I had to manualy tweak certain games/programs to only use cpu cores on a numa node basis.
eg for single threaded and dual thread games I would set the affinity mask to the last 2 cores to get them running sweetly.
Now with win7 it has set up numa with out any OS tweaks, and games etc apps seem to do the right thing..eg no threads hopping to different numa nodes.
An of course the old opties have all VT stuff to get winxp compatabilty mode working at full speed
Though it does till have the annonying, logitech bluetooth mouse failing asleep intermittently if the cpu's go into a lower power state.(same as xp pro 64)
