Hello, this is my first post sorry if me English isn't good enough I'm from Spain.

Well, here is my question.
I have been waiting for new maxwell cards since a year and now that I can do a 980 SLI with HDMI 2.0 I listen that 4 GB of Vram isn't quite enough for 4K gaming even with low filters like 2xMSAA, now I heard news that Shadow of Mordor and Evil Withing would need at least 4 GB of Vram.
My point is I would love to target 60 fps 4K gaming in witcher 3 and high end graphics quality next-gen gaming.

Someone know if with de Nvidia compression that improves memory usage or something?

And if I have to wait to 900 Titan or 2 way sli 980 or maybe 3 would be good?

PD: I know that Vram doesn't plus if a put a SLI I'm saying if 4 GB would be enough.

vram doesnt stack in crossfire/sli setup, meaning 3 cards with 4gb memory each in cf/sli count still as 4gb, not 12
no idea if 4gb is enough for 4k gaming though,i would say it is
also i am not sure 2 cards would be enough for max settings at 4k resolution for 60fps

Hey,

4K might sound appealing but it's still a gimmick. You'd be better of playing on a lower resolution with high FPS and all settings on Ultra then playing on 4K but having to reduce quality settings and playing with low FPS.

And since you are asking for demanding games take a look at this:

It Takes 2 gtx 980's to run Real 4k. The youtube video shows no proof of a single any card running 4k. IT takes Two R9 290x,
Two gtx 780Ti, or 2gtx 980's. Yes theoretically 3x sli Gtx 980 shoul be better. Do your home work first.
2x proof.

I have two 980s in SLI and a 4k TV... and all I can say is that I'm not entirely impressed. Sure I can play at 4k, but I generally have to turn down so many other awesome settings (shadows, SSAO, God Rays, PhysX, etc). Perhaps the games are not optimized well? The ones that do run decently are games like Tomb Raider. Assassin's Creed is a drag because I have to lower my settings. I never use AA because it is not needed with 4k, and that does help a little.

What I've decided to do in the mean time until a 900 series is released with more than 4GB of VRAM, is set the games to 1440p and max out everything else. Witcher 2 plays beautifully this way, even with Ubersampling, so its almost like playing in 4k. (At actual 4k, the Witcher 2, is completely unplayable for some reason). My TV upscales it automatically to 4k so it really doesn't look bad at all. With AA activated at 1440p the games look great, and run great.
