David, can you tell us which PCI Express display cards ARE well behaved? 
I use a pair of CRT monitors (21" Trinitrons) on a Windows XP Pro 
machine, connected to a dual head Radion X1300/X1550 Series display card.

Using Spyder2Pro, along with the Microsoft Color Control Panel Applet, I 
can't get both monitors to match exactly -- the plain grey desktop has a 
different hue on the two screens, and an image opened in Photoshop 
spread across both screens shows a slight shift in colour from one 
screen to the other.

I surmise that the display card is not doing its colour management job 
properly, and wonder whether this is a known issue with this particular 
card.
