I've done some reading and it appears Ghost is just a horribly optimized console port that will use all the Vram available.  Regardless I still enjoy playing it but the random stutter is driving me nuts.  What settings should I try to turn down to help use less Vram?
 

So try 2 x txaa or something else?

I apologize for my ignorance, is AA Txaa? Is Msaa less demanding?

Typically FXAA is the least intensive AA method games have these days, but it can sometimes make things look a bit fuzzy.
 
With your triple monitor set up you might not even be able to run even the lowest level of AA due to tripling your resolution.

I have not played Ghosts in a while... but I have messed around with COD:AW settings for a while now. The best way I have found to comfortably change settings and find what fits me the best is to run MSI Afterburner so I can see everything while i'm running the game. I watch my GPU and CPU frequency, load percentages, RAM usage, VRAM usage, FPS and frame timing. In COD Ghosts you should be able to just about max everything out... but I've also found that SLI caused annoying stuttering issues for me when running two GTX 970's. 
 
You might want to just try running one card and see how your experience is.
 
Also... they do push updates to the game and change things up from time to time... I know they did that with COD:AW. Sometimes I log on and i'm getting smooth games and having a lot of fun... sometimes the lag is so bad and the game is running like crap.

I played for about an hour using 4xMSAA.  It seemed much smoother and Vram stayed between 2700-2800mb.  I don't know why 4xTXAA was hitting 3000mb.  It seems good for now.  If it hits 3000mb again I will lower it to 2xMSAA.
