I have a Big Bang XPOWER X58 motherboard in this motherboard i wanted to put six GPU in the board then the question arises every GPU has it's own HDMI or VGA output ports then tell me is it possible to all GPU will display in the single monitor or not and why people can use multi GPU's in the boards.
you will NOT fit 6 high end graphics cards in that board without water cooling all of them as any decent graphics card takes 2 slots in space.
2nd even if you did manage to cram 6 crappy or 6 good with water cooling the MAXIMUM you can crossfire / sli together (so their power stacks) is 4.
so you would be left with 6 graphics cards running by them selves. e.g. you open a game in 1 screen, it will use ONLY the graphics card that its plugged into.
4 linked graphics cards will be your max (AMD or Nvidia) im sorry
It means if i am using multi GPU in the single board then i have to plug the monitor cable only in the one GPU and the all other GPU will process the graphics on that single monitor which is connected with the GPU through to the cable.
