NVS 290 worked fine with dualhead via DVI, however it's 3d performance was 
too sluggish for me so had to swap it for a Quadro 600. It gets around 
9000 fps with glxgears compared to 2500 fps on the NVS 290.

With the NVS 290, enabling compiz slowed down OpenGL stuff so much that I 
just couldn't live with it. User experience is silky smooth now. The 600 
card I got had one DisplayPort and one DVI so I had to venture with a 
DP->DVI dongle. No problems there. Haven't found myself wanting 
triplehead yet.

I've practically always had a nVidia in my workstation. No clue about the 
current state of AMD GPU support in Linux these days.
