I also think the 3gb of vram will be limiting in some games

3 GB is usually enough for that resolution (whereas the 2 GB of many 960s was NOT really enough during the second half of that card's prominence), though there are some games with ultra high texture packs that will blow through 3 GB of RAM

3 GB of VRAM is definitely enough for gaming at 1080p, and is only at most a 10% performance difference to the 6 GB version usually a 5% difference since it has fewer CUDA cores than the 6 GB version

Upgraded from gtx 970 4gb

Great starter but the 3 gb will cause bride fram drops when it maxes out I would recommend the 6 gb version to all I upgraded to it and its awesome.

3GB will often not be enough for most games while 6GB is always more then enough and gives some future proofing

Dual fan cooling, back-plate protection, 6GB

I also own a 1060 3gb in my other system, its almost equally as good as the 6gb card but will most likely be hindered by its 3gb of vram in the near future, so I highly recommend this gpu.
