As a rumor is looks good (so a beast of a GPU), but why would AMD go with 4GB of VRAM when some current games are already asking for more?

^ This.

We really need more than 4gb of vram my 780ti tri sli is crying... its godly power is held back by its miniscule vram at 4k.

Well not really, only in a few games I've had to turn down textures a bit, but 6gb vram will soon become the norm for 4k gaming.

Actually, RAM is not much of a bottleneck with the actual cards. Some board partners have launched 8GB versions of the 290X and at least the Sapphire one doesn't perform so much better than a 4GB regular one.

(note that both are clocked at the same speeds)

 

But I was thinking more about the games asking for more than 4GB of VRAM to use the highest settings.
