I have the 2XAGP and a older PCI
graphic card called TwinTurbo.
But I will get me a better one, its a little slow... but it runs.
The smart thing with OS mode
is if you have another monitor
it is just to drag whatever you have
to the other screen. (just like you do
in other apps.
(the bad thing)

if you have a mixer, or synth placed on screen2 . next time you open the song its on the first screen.
and you must drag the synth back to the other screen.
. but hey. the new 3.1 OS will be released soon. and I think it will be a great update.
