It's probably a safe bet that the answer to the question of how much vram a 3x1 eyefinity configuration of these panels would take is basically As Much As Humanly Possible
Simply storing a *single* raw frame of framebuffer data for 3 of these would take 32MB of space (compared to, say, 6MB for a single 1080P image) - and there are many such frames stored at any one time, not to mention all kinds of other data related to pixel size... you *might* get away with 2GB, but the thing to keep in mind is that with multi-gpu solutions you don't get to add up your total memory; each card needs to store an effectively full copy of all data, so you've only got 2GB effective (not 4GB) - 3GB would be a much safer bet.

But "Nvidia sais"
I have no idea myself.
4 1920x1080 windows is only 12% more pixels than *2* of these monitors - and when it comes to memory scaling limits adding more cards won't really help you so... Edited by siberx - 3/21/12 at 3:50pm
