I recently bought a Zotac GTX 680 2GB. I could have gotten the EVGA 4GB version for $60 more. I only run 1 screen at 1080p and no plans to go higher than 1080p or multiscreen. Even if I did buy the 4GB version I still would plan on upgrading to the GK110 or whatever the next high-end GTX card is maybe a few months after it's out and selling my GTX 680. I also have no plans to SLI. Should I have bought the 4GB version?
