So Im considering purchasing a Gigabyte GTX 770 Windforce in the 2gb variant with a 1080p display. In the near future however, I am planning on buying at least a 2560x1080 res monitor ang getting a second card. Would the 2gb variant be enough memory in SLI to sustain resolutions equal to that, or most likely higher?
If you want to run larger resolutions get the 4Gb card(s), its only $50 more. Adding another card in SLI does not increase the amount of usable vram. With 2 2Gb cards in SLI you will still only have 2Gb of usable vram.
