It happens I´ve too much time on my hands today, it´s a bank holiday
I´d have spent adding something to my showreel, unfortunately I ignored
the fact that all I´ve left at home is a pretty much naked barebone stripped
of anything more usefull than that plain old notepad...so, no fancy 
pictures.

The last resort furry glove massage, (sc)rubbing desperately doesn´t help 
it,
I´ll have to postpone it some more...until I´ve my gear back. Ah, 
Fr(y)idays...

But to get back from OT:

How about the display refreshrate set for the boxx machine?

When re-installing nVidia drivers, it´s usually set to "best",
e.g. maybe you´re hammering your display with 80-100HZ,
while your laptop is feed with 60Hz and a lower resolution?

At least with games this may well give a difference in performance,
as well does AA, which I think the Quadro drivers have set to "on"
often, meaning you´ll actually have at least double the pixelresolution
processed for every frame.

Did you try to select the "softimage" or "xsi" preset in the nVidia
quadro driver settings? Do you have AA set to "off" instead to
"by application"? In case you run a TFT instead a CRT, you´ll
most likely won´t have to check the refresh rate, it´ll be 60HZ
but it´s still worth to check that you run in true color mode instead
of (default on install?) 16bit mode, which could also confuse your boxx.

Cheers

tim
