even using the new motherboards with crossfire x or the nvidia equivelent supporting four gpu's it can't be done you would need 2 motherboards to achieve that.

you could certainly use eight monitors with the right kit but i'm not sure how stable that would be i would probably want 2 or 3 computers linked in parrallel doing that with the gpu's mixed in.

and there is driver support from either Nvidia or Ati they themselves may not support that many monitors.

going to ask now though i'm interested to know if they support it

why do you "Need" This?

well ya it's possible, but like they said, not with 1 computer..you'll need 2.. or 3. and some expensive stuff in order to run 3 cards on each.. Look into maybe getting Quad Screen Systems. and buy 2 Quad sets.

Quad Monitor Displays - Multi-Screen 4 Monitors

or get these. Where theres 4 shaped in a Square, instead of 4 in a row. get 2 sets of the 4 shaped in a Square for a total of 8. that would be nice.

Time to break out the Plastic..

ya but that makes the Quality suck.. if it's for work, or graphics and software, he needs it lookin good.
