Hey sorry i forgot about but
I got a adapter so i can use the carpc in the house and i Did a test on my MII6000E
I'm using the standard Onboard video for my dual screen
I set the VGA as screen 1 and Video out (composite) as screen 2
Then i set Mediacar on the first screen and had mp3 and d3 GPS going at the same time.
I then opened 3 winamp windows on the second monitor (the composite LCD) and had them all running and i didn't see ANY slowdown at all
And my board is a 600mhz Fanless Mini ITX
All stock to no addon video card or anything and it ran great
I even had usb speakers plugged in and had the 3 winamps output to them it was good
Also ultramon was the program sorry

dodgetimes2 was right
