Question About VRAM, SLI, and Triple Monitors

Hi all

I am looking into doing a triple monitor setup in the near future and was unsure about something. I currently have a single GTX 670 FTW (2 GB VRAM) and would obviously need to SLI that. I know VRAM doesn't stack, but could I get a GTX 670 4 GB and SLI with that? And would 4GB be enough for a triple monitor setup? Ultimately I'd like 1440p monitors, but would be find settling with 1080p. Just unsure if having two different VRAM cards would be an issue.

Thanks!

Oh and anyone have any recommendations for super thin bezel monitors? The posts I've seen point to ones that still seem to big to me (I don't know how small they can get)

There will only be 2GB available out of the 4 since the lower equipped card will become the default.

Man :(  I was afraid that was the case but hoping it wasn't. 2GB VRAM isn't enough to run triple monitors is it?

From what I have read, you are able to SLi two graphic cards as long as they have the same GPU, in this case the GTX 670 and that VRAM is not counted. HOWEVER, if you are able to do this, you will be limited by the least available VRAM, as each GPU must have the same things loaded into memory, and therefore even if you had a 2 GB card and a 4 GB card you are limited to 2GB per card.
Note: I do not have much experience with SLi, all of my multi-GPU experience is with Crossfire. However, I am fairly certain what I have stated is correct.

4GB should be plenty for 5760x1080. I run two 7950 3GB across 3 1080p screens and have no problems playing most games near max settings (turning down shadows and AA and I can play everything maxed across three screens on BF3, for example). However, remember that you would be limited to 2GB with your current setup, which would be cutting it close for 5760x1080, and definitely not good enough for 3 1440p screens.

It is but you can not turn up all eyecandy like you can with more Vram.

Dang! Should have done my research and bought a 4GB card to begin with. Thanks guys!
