It's not easy to say. For 1920 x 1080, it shouldn't really be much of an issue, probably for at least a year from now even, but I personally would be happier with at least 4 GB.
If anyone asked me to recommend a $200 card, I'd say go for a 4 GB 480 and consider the 3 GB 1060 if you cannot find a 480 and need a card ASAP, or if the asker doesn't care about ultra/very high textures.
Still, there is still the question of what the 3 GB 1060 is, exactly. Is it a normal 1060 with less memory or also a less powerful GPU, as the rumors say?
If the latter, then it should be priced at $150-170.
