Are there any motherboards supporting two AGP slots?
Is there a way to utilize two video cards or motherboards for enhancement of a single display
(better graphics)?

Baileygirl,

Don't know about two agp slots.  You CAN run two video cards... but they have to be the same mfgr using the same drivers, I understrand.  One obviously will be PCI.... which will be ther determining factor on framerates.

Matrox makes a agp card they call the parahelic...... drives three separate monitors.

Many use a networked set of PC's using FSUIPC with Wide FS and Wideview.  Then if you have "screaming PC's" driving each view...... it'll run fast.

Somewhere mixed in the conglomerate "Homebrew Cockpits" thread some of this stuff is mentioned, I think.

best,
