Right now I run 1440p windows in ultra with viewers to the side. Vram is ~ 5gb (don't remember exact number) and gpu load is less than half.
GTA V runs over 90% load and ~ 5.2 gb vram.
If you're still checking this thread, then I'd like a test to be run. The 980 Ti comes out in ~1 week, and I need to know whether 6GB will be a limiting factor for me when running a 2160 resolution. I fear that it will be, but I'd like to make sure before I drop the big dollars on multiple Titan Xs.

I'd like to know the GPU load and VRAM usage in a few different situations (preferably read with GPU-Z).

Number of Clients: 5
Resolution: 3840x2160
API: DirectX 11
In-game Presets: Ultra/High/Good
Framerate: 60/30 and 60/20
Location: Draenor (Shadowmoon Valley) > Draenor (Nagrand) > Pandaria (Jade Forest) > Elwynn Forest (in order of my preference—you only need to choose one)
Camera Angle: They don't have to be perfectly aligned, but I'd prefer them to be looking in the same direction as whichever location/screenshot you choose, and not zoomed in and staring at the ground. The load on the GPU can change drastically depending on which direction the camera is looking.
Other: Responsiveness/Choppiness of the game clients if you're pushing max load/VRAM, and whether you were running 60/30 or 60/20. Long stuttering? Hard lock-ups for 2-3 seconds? Smooth sailing?

I'd prefer it if you ran around in a circle or something for a moment when testing to let all of the game clients eat up their surrounding area and load it into the VRAM—This will also reveal if there is any stuttering. I will also ask that you log out to the character selection screen after changing in-game video setting presets because I don't know how well the game client is going to flush/purge what it doesn't need in the VRAM when it has so much available, and logging all the way out to the character selection screen should force that to happen.

I think that's it—Thanks.

This is a late reply, but seeing as two GTX 980s is only worth 4GB of VRAM, you're probably going to be hitting the limit quicker than you want.
