2Gb for the gtx680 isn't a bit low ?

[venur]

I'm going for a 3 monitor set-up and like many I'm waiting to see how the futur Nvidia GPUs will perform before making my mind. I'm going for either CF hd7970 or sli gtx680 so its 6GB vs 4GB. As for the games of today I'm pretty sure 4gb would be enough to run anything on ultra setting 4AA but I fear about the futur.

Anyone else think that 2gb on such a powerfull GPU might prevent the card to reach its full potential ?

From what I understand, when use SLI or CF, you will only be able to use half of the total amount. So you would be looking at 3GB or 2 GB.

Video memory does not combine in multi-card setups.

2gb Vram + 2GB Vram in CF/SLI do not = 4gb Vram it still stays the same as with one single card. 3GB Vram is what you need to run any game flawlessly on three monitors in eyeftnity.

I know a guy who plays BF3 at 1200x5760 high (With a Radeon HD 7970 45fps give or take) and at Ultra settings BF3 needs 1.25GB of VRAM with a single 1080p setup. The benchmarks will tell for sure which card is better at 3 x monitors but so far the math is not on Nvidia's side.

oh lol I thought they where adding. Then I don't have to wait for Nvidia anymore I guess. No way I want to spent over 1000$ in GPUs to be stock at 2GB vram.

Some people are claiming that they are running 5760x1080P with SLI GTX 580s 1.5gb Vram with no problems but I am not sure how much truth is behind it.
