Memory for Multimonitor Displays

When running multiple displays off of one or two video cards, what would impact not being able to push output to 6+ monitors?

Example:
My motherboard has two PCI-E 2.0 16x lanes.
I install a Nvidia Quadro which has a dongle that physically has 4 DVI-D out ports.

My computer is quite standard with specs of 4GB of RAM/3.0GHZ Dual Core CPU.

The video card has 3GB of on-board GDDR5 Ram with high clock and memory speeds.

Would the limitation of being able to output to 6+ monitors be affected by system ram or on-board video ram or CPU clock-speed? Or a combination of both.

Im kind of baffled as to which memory is responsible for holding the image as it is streamed to the screen/s.

Onboard RAM is not a factor in 2D applications - where it comes into play is in 3D games that use large textures; accessing the textures on the card is much faster than in system RAM.

Are you having an actual problem with multiple monitor displays, or is this a precautionary question before you jump into the water?

This was an issue a while ago where I was trying to setup 8 monitors via two nvida quadro cards.

Only two displays would eventually show up after about 30 minutes and that would be only during the Windows is now starting screen.

I eventually gave up and just got two big monitors instead.

So according to your response, I couldn't have a computer with 512MB of system RAM and a Nvidia GTX 580 (provided my motherboard supported the card) and run multiple displays because since the windows desktop is a 2D shell and would certainly die due to the lack of system ram?

No, I am saying the RAM on the card is not relevant to performance when you're talking about 2D applications, with the exception of Photoshop, which might benefit a little.  Windows XP can manage up to 10 displays, so 8 should be no problem - I see them all the time on trading floors.
