Thanx for the answer I put a line in the wiki for this,can you describe Mac

The most thing I am suspect is the signal quality, is there a difference in
noise floor of SVGA-Outputs and is it possible to drive long cables to
projectors on a stage etc... since I never did.

Using PCI-Express or also Known 2 PEG Slots on a nforce4 chipset mainboard,
you can drive two cards with SLI Link (I think only nvidia has this) as one
with four heads... I have read never tried ?-)
