AMD trolls Nvidia HARD over GTX 970 memory fiasco.

They owned them hard, and yes Nvidia made themselves an easy target for AMD.
 
Good good. How can NVIDIA call their GPUs next gen with that little bitty bit of VRAM.

That's not really what it's about. It has to do with how GTX 970 VRAM access between the SM's is done. Since 970 has less SM's than 980 access to the last 512MB of the 4GB of VRAM has severe performance penalties.
