That depends! How many monitors do you use, or plan to use, and of what resolutions are they/will they be?
I play on one monitor at 1920x1080. I would play typical games like battfield, doom, COD, CSGO etc
On a single 1080p monitor I don't see any reason to go with a 6GB for VRAM alone. Maybe if you plan to get more monitors, or higher def monitors, but 3GB is really great for 1080p gaming.
That said, do note what was mentioned ealrier about VRAM not being the only difference between some 3GB and 6GB cards. Some 6GB have better specs in general.
