I am embarrassed to even admit this, I only did this once! Using
my PowerBook G3 I connected it to the client's monitor and created a
profile. She was also on a Mac. Then I moved the profile over to
her Mac. Was not bad. Was not perfection. And I learned never
ever to do that again! The video card in the PowerBook G3 and the
video card in her Mac, of course, were not the same. To answer the
question, yes, there was a difference due to a video card.
When profiling a monitor, one is profiling the monitor/video card
combination. Can't get away from it. They are a team. A pair.

another
computer may not work so well. If you can, switch the video card as
well.
Has anyone actually ever seen a difference due to a video card ?
Unless they have some sort of "enhancement" image processing setting
engaged,
they should be interchangable, since they are nothing more than a
frame
buffer and a linear D/A converted (or not even that if it's a
digital connection to the display). Differences between 8 bit
D/A converters is not something that is likely to be captured
easily by calibration, since you'd be hard pressed with modern
technology
to produce an 8 bit converter that wasn't accurate to better than
0.5 lsb, and display variation and instrument repeatability errors
will swamp this.
