I'll agree completely with this.

Anyone using Trident cards deserves the pain they get.

I'm not very keen on them myself.

The "newer" ATI cards have problems.. but I've had no problems with older ATI
chipsets. Older Radeons (pre 7000) and Mach64 et. al seem to work just fine.

You and your Matrox. Yeah, the Milleniums were a slick card in their day. I've
not tried the newer multi-head cards, but they are the most promising. If
you want a fairly foolproof card, consider these - but be prepared to pay.

I'll attest to the crashing. They will either "just work" right out of the
box, or won't work at all without some AGP tricks and tweaks. Forget about GL
across anything more than two monitors at a time (with TwinView support). If
you plan on using Xinerama, forget GL altogether.
