EVGA GTX 770 2GB vs Gigabyte GTX 770 4GB worth the extra $50?

[Alsharad]

I'm building this PC and I'm not sure if I would pay an extra $50 to get the 4GB version.
What do you recommend? EVGA GTX 770 2GB or Gigabyte GTX 770 4GB?
Will the 4GB be enough for triple monitor gaming?

I am also planing on getting another one for SLI after few months.

If you plan on using multiple monitors, or going up to an extreme resolution, the 4GB will suit your needs since you plan on SLIing in the future.

If not, and you're playing on a single 1080p-1440p monitor, 2GB should suffice.

You might as well save up a but more and go for the gtx 780. The 770 is only 256-bit and it won't be able to utilize the 4gb VRAM. But if you want gtx 770, take 4gb version then SLI it in the future(if possible).
