amd 6400X2 3.2ghz, 9600 video, 4G ram (shows like 3.6 cause I have .5 ready boost extra). Far from great but good enough for 7 clients at 1280 X 960 most stuff off.

Its the 3.2ghz speed that makes my stuff look better. So 6 computers like that with 7 X 5 and the main by himself at 1600 X 1200 everything cept shadows on.
