Yes. It should just treat it as two 2gb cards.

So the 4gb card will be useless?

That looks a little outdated on this particular question. That talks about the Geforce 7800 and the 256mb and 512mb versions having different GPU chips. As far as I am aware that is no longer the case, and the only difference in the new cards is the amount of Vram. Basically what it should do from my understanding is ignore the extra vram on the second card. You will get the boost in performance from the second card, but will only have 2gb vram usable. Keep in mind when putting cards into crossfire/sli the vram does not add up, a pair of 2gb cards equals a more powerful 2gb card, not a 4gb card.

Thank you, that answered my question seamlessly. Another question if you dont mind. I learned that sli doesnt stack vram. But vram is needed for higher resolution. So if i have multiple monitors, sli with only 2gb per card wouldnt help? What if i have a single monitor with 1440p resolution (or more) sli is also useless? As it oly gives 2gb

I am realy confused now, upon searching other forums, they say sli/crossfire is beneficial with higher resolutions and multiple monitor setup. But if it doesnt stack vram how can it help?

Because vram is far from the only factor in performance. Two cards is far more performance than a single card.

Sorry if i have too many questions, and thank you for your help. So the answer is, 2 cards will sure boost performance without sacrificing resolution? Let say 2 monitors with 1440p is alright with gtx760 2gb sli?

As the resolution goes up the graphic card/s need more memory to work in-it's like a workbench, the bigger the work piece (the frame) the larger the bench (memory) has to be to hold it.
For a pair of 1440 monitors you'll need 4Gb cards.
