When the "tons of people" were arguing for 4 GB 680s over the 2 GB models, actual published testing could find no significant difference in performance

When the GPU is already bottlenecked by memory bandwidth, adding more memory provides little to no performance benefits. This should not surprise anybody but bigger numbers still seem more futureproof. For only a few extra bucks, these often fall in the "why not" or "might as well" pricing range: better off spending $30 on an extra 2GB of VRAM that might never yield any performance benefits than regretting your $250 purchase for trying to shave $30 off the price.
